Well there's all different kinds of studio interference. They fired the directors of Solo for one. But I haven't heard much about them dictating plot points or character beats directly, that's not the normal way things work.
Honestly I'm not encouraging people to harass Rian Johnson more, who I think is a good director even if I didn't like his Star Wars film overall, but as far as I can tell the buck stops there for Last Jedi. I assume the same is true of Rise of Skywalker and Abrams, he certainly seems to be in charge of his films, but we're all guessing.
I feel like it's weird to blame the producers in the absence of evidence. Nobody's shaking their fist at Ivan Reitman for Ghostbusters 2016. Or... Charles Roven...? Whoever that is, for Batman v Superman. Or a whole bunch of people I've never heard of for the Bay Transformers films. For some reason everyone likes to dump on Kathleen Kennedy for Star Wars though.

True I suppose, but it's not like writers don't have plenty of nonsense at their disposal already in the Star Wars universe.
