Couple this with a lack of overall direction and the aforementioned autists either no longer working there or not being listened to, and you have a fictional universe where you need to consoom everything to have some idea of what's going on, but there are so many inconsistencies and retcons from writers just doing whatever the fuck they want that it's basically impossible to get the overall picture.
Also known as the MCU syndrome. Really, people practically asked for that after giving the MCU such rave reviews. Now Star Wars is taking the same direction, which means that if some jobber wants to know what's going on in Ahsoka, they'll have to watch TCW, Rebels, the Boba Fett show, and three seasons of Mando. Good luck.
As for writer inconsistency, that has always been a problem with SW, but the canon hierarchy works to keep that in check. If you believe that Karen Traviss' writing is bullshit and Legacy of the Force shouldn't exist, you can skip from the NJO novels right to the Legacy comics and pretend that nothing important happened between them. You can't do the same for the new canon.
Of course, many of these writers are just using it as an excuse to tell their stories, which is how you get shit like fart weddings and long discussions about how female soldiers menstruate.
That's actually kind of funny. Female soldiers menstruating would just give commanders another reason to hire male soldiers exclusively. Like I said before, Disney Star Wars has a history of accidentally being based, even though they don't want to be. Ahsoka, the show exclusively about female Jedi, was upstaged by male characters like Baylan and Anakin. The Sequels showed us that the Second Amendment saved the galaxy, as it is citizens with arms, not the government, which saves everyone from fascism.
The EU had distinct canonical levels, from basically non-canon at the bottom all the way up to the movies at the top, with anything George directly stated being equivalent to or above the movies themselves. If two works referred to the same events, the higher level superseded it. They also had lore autists working diligently to ensure that any new EU works could fit in to the whole picture without fucking things up too seriously. The result is a universe where a fan can delve as deep as they want to without being required to. If all you cared about was the movies, you could watch them from start to finish and have a complete story. If you wanted further adventures, that's what the EU was for, branching off into many directions.
Lore autists are an important part of any sci-fi franchise. Hence why the old SWEU had a sense of consistency that modern SW and other lores did not. They either have retcons and resets like American capeshit, or they go the Warhammer 40K route and say that nothing is canon so that any author is free to do as they wished.
Honestly, I think the loss of the EU and alternate media between Clone Wars trilogy to the Rey trilogy is partially contributory to why the new trilogy isn't as well regarded. The prequels had their share of problems to be certain, but George Lucas wasn't stupid. He knew damn well the tie-in games and novels would keep the fans there, so he took great care to let then flourish. He very famously was open to alternate works so long as they followed basic rules like "no time travel" and "no naming Yoda's species ya dweebs". And for all of problems the prequels had, Lucas still nailed a lot of the tiny worldbuilding elements and created a setting that felt open to those sorts of works.
Even as the Prequels were being panned by the critics, fans were enjoying the films and loving the SWEU works, from KOTOR to Republic Commando, to the comics and novels. Star Wars was depicted as a living universe, and Lucas even made it so that the Prequels had nods and winks to the SWEU, which implied that the SWEU and the Prequels were in canon with each other. That was the proper way of making a sci-fi universe.
Disney instead decided to make literally everything the same level of canon, which gave them an excuse to not bother actually telling complete stories because some other writer hired for peanuts will come along later and fill in the blanks.
That's the problem with all parts being supposedly canon. In the end, it is not. Some comic or novel written in the past can be overridden by someone like Dave Filoni who wants to tell his own story of how Ahsoka fared in Mandalore or how Caleb Dune saw his master die.
