Your criticism is on point but I believe that the audience has changed. I think the new Trek shows are trying get more younger viewers by having a less involved plot but still try to appeal to OG Trekkies by having characters such as Picard, Riker, Pike and Spock.
TNG had decent ratings but the studio executives were always trying to find a way to make it more mainstream. I don’t know if a TNG or DS9-type show would be able to net the kind of ratings that the studio require to stay viable.
