If it were directly from the company, it is marketing.
In the first video, at 4:04 onward, the reviewer described the First Devastator War between TFC and MT. At that time, TFC was 'king' and MT a contender. TFC came out with Hercules first. MT realized fans wanted G1-style and announced Giant. It was a huge hit. To fight back, TFC had to introduce an upgrade kit to make its figure more G1. MT took this opportunity to turn online fans against TFC. 'Virtually overnight', everyone turned away from TFC and towards MT. TFC never recovered from this loss in reputation. A new king was born.
I remembered Spencer mentioned in his Bobby Skullface interview that MT was very concerned about its image online. In the early days, companies were more prone to using 'fans' to raise the company image.
This could be why NewAge refused to sell new legs separately for its Agamemnon (Megatron). But then MMC doesn't care and sells its Assaultus upgrade kit so expensively. I wonder what's the reaction in Chinese forums today.
I can tell you straightway that, watching some of his reviews, this reviewer does not like MMC -- mainly due to its high pricing.
The reviewer wrote this sort-of like a historical 'documentary' (from what he knew) and has an earlier video talking about FPJ: 【变百科】史上最悲催第三方, 物极必反的FPJ
(The saddest 3P in history, the peak and decline of FPJ.)
Basically, he said FPJ kept wanting to do its own thing after it got recognition from Transformers fans, but they weren't buying into it, so ultimately it just faded away.
I think there's no more room for 3P in CHUG, that's why they had to move on.
The whole 变百科 is worth watching.
Two-part series on UniqueToys:
Its beginnings and early challenges. Its greatest work (to date) Ragnaros (Bruticus) was upstaged by TW's Armageddon and they had to rush it out. [Now we know why the limbs weren't as refined as the legs.] In the end, UT found it was tricked when TW finally revealed it was using the pants approach.
UT refocused on movie stuff and collaborated with DX9 to overcome its weakness in aesthetics. The last part shifted to DX9 and he said DX9 had an ace up its sleeve, but he left it as a cliffhanger.
The very first 3P Legend figures were the VIP three Datsun brothers by ARK Studio. (Its designer was well known as 'the god of scale'.) It was not successful. DX9 saw the potential and followed with its ace -- its War in Pocket series. UniqueToys joined in the fun. Good times did not last. Both were forced to stop due to over-KO'ing. One particular KOer was especially lethal. UT 'died' first, leaving DX9 to fight alone. But even DX9 found it harder and harder to 'live'. DX9's last WiP was Dutch (Optimus Prime) as a send-off, and it was KO'ed too. The lethal KOer was revealed to be MFT. And MFT was allied with the designer of ARK Studio.
MFT is revealed to be backed by Machine Boy (a big organization with vast experience with 4P/KO Transformers). MFT planned to dominate the Legends market by having both original designs and KO'ing its competitors: DX9, UT, MST and even IronFactory. It went with Legends+ scale for a few reasons.
Hot Soldiers was supposed to be its original brand, led by ex-designer from ARK Studio. The reviewer explained why HS started at 03. But HS products weren't very well designed, despite what its designer may think. It accumulated at HS-09 Big Yellow Bee (Bumblebee), which received harsh criticism due to its open back. The designer hit back with a number of points, one of which was that "no one is capable of making a 6cm Bumblebee". And this would be his undoing.
Where was the DX9 WiP designer? Where was the UT designer? They were not idling, but were sharpening their swords to challenge MFT once more.
What is the relationship between DX9 and New Age? It's too long to explain [his words, not mine], but New Age is undeniably DX9 WiP designer. ("It's him!")
New Age's first release was a 6.0cm Bumblebee. It had good looks, good transformation, good material and was well-made. It made NA famous overnight. And it was also a slap on HS designer's face, who once claimed it was impossible ('no one is capable of making a 6cm Bumblebee').
This was extremely significant because it showed 'the god of scale' was not infallible after all. Previously, his word on scale was taken as gospel.
With NA-H1 Flipper (Bumblebee), NA established a new Legends- scale. MFT would not be able to dictate the Legends market. NA went on to do very well.
When NA came out with the Datsun three brothers, MFT released their own using updated VIP design. It was supposed to be HS-17, but later branded as Iron Trans. Only the designer knew why.
Flipper was KO'ed by KBB and UI. Due to popularity of MFT, many people thought these were original designs. The reviewer had no heart to tell them the truth when he saw people playing happily with these. Some were aware of MFT, but not NA. The irony of being original.
At one time, Jizai announced they were going to KO NA Ratchet/Iron Hide, but then they dropped it quietly. The reviewer speculated Jizai wanted to buy the blueprint from NA (common practice in 3P; this is 'KO' to the outside world), but NA didn't want to sell.
[Followed by a short review on Agamemnon (Megatron), Insecticons and seekers.]
The DX9 WiP designer who was once 'beaten to near death' had come back. But where was his Legends ex-companion? Was he still a friend, or was he a foe now?
An intro of Magic Square designer. He was a former DJ and had no formal training in design. But he loved combiners and tinkered with existing combiners to improve them or create new ones. His work was noticed by 3P companies and he joined Unique Toys. Ragnaros was designed by him. After that, he left and set up his own design studio, Magic Square. And one of the first things he wanted to do was Menasor, something he was not able to do in MP scale in the past. He revealed the fourth version of his Menasor in the 2019 Shanghai Toy Show.
What this tells me: (i) we will see Legends Menasor. This is a given since the last reveal; (ii) I don't think we will see any MP-scale figures from MST any time soon. His focus is on Legends.
[Note: from his other reviews, I gather the reviewer is a friend of the MST designer.]
