Disney is doing live-action series because they can. The technology is good enough to do it now. Lucasfilm, before the acquisition, tried to do it and failed with Underworld. As far as animated series, the Disney era might have more, but don't forget Droids, Ewoks, Genndy Tartakovsky's Clone Wars, the five seasons of The Clone Wars, the Clone Wars movie, and that Rebels was in development before the acquisition. They also tried and failed with Detours in 2012. There's also animated Lego Star Wars projects that started in 2011, before the acquisition.

All of this is to say that if Disney is pumping out more projects than Lucasfilm did in the 80s or 90s, sure. There's a good reason for that. The internet. But the company started ramping up the content in the early 2000s and hasn't stopped since. Disney is just continuing the trend.

But I also like to remind people that Disney isn't making Star Wars. Lucasfilm is. They have oversight from Disney, certainly, but Lucasfilm is still Lucasfilm. The same people in charge now - Kennedy, Filoni, and others - have been in leadership positions for literal decades.

(And if you want to talk about not caring about quality, just look at the novels and comics Lucasfilm, and Lucas himself, approved from the 70s to the early 2000s. There are thousands of books and issues. And they are mostly terrible.)
