Anime is fine, it's not nor ever really has been in any trouble in of itself. It's a medium like any other, and within that medium you get a lot of garbage along with the real gems. Truthfully one of the things that actually helps it is specifically that it's full of obsessives, as one of the big selling points of Anime is the willingness to go into odd territories and work with concepts and characterizations that people working with other mediums usually won't touch. Sometimes it works, sometimes it doesn't, and a lot of times the rush work and budget contraints ruin things that would have succeed otherwise.
I'll also say that in reading this Miyazaki comes across as something of an idiot. I say this because he's a guy whose successful work is movies, as in singular products that are at best a couple of hours long and tell a contained story in that period of time. He by and large can't really criticize the medium when most anime is designed for televised viewing and to take place over a much longer period, part of the reason why a lot of things stay so static is that in theory a viewer can miss a few episodes and still pick back up on what's happening. Most of the major changes to the formula and eventual revelations still happening within the last few episodes, where again even with a 30 minute show might see things drawn out over the time frame of an entire Miyuzaki production if say your 26 episode series has the finale/resolution spread over 4 episodes which is where the status quo is shook up.
What's more I'll say that Anime has always had a lot of garbage, it's just that those of us outside of Japan became spoiled when Anime first began to circulate globally as it was only the very best stuff that was generally seeing translation and release. A lot of things that sounded cool, and saw release after pressure tend to be less than thrilling when they finally enter the global market, and to be fair with the race to try and localize as much as possible for international sales, we've seen ever increasing amounts of garbage filling the market. It's not so much any real change in the industry (if some of you are interpreting what Miyuzaki is saying in terms of the products of the last several years) as much as it is the being wedged upon to the world with few real standards being enforced, not to mention companies increasingly caring less about integrity (though there are still exceptions) and censoring mediocre works down to the point where they become terrible.
In short it sounds like this guy is an elitist, and a hypocrite given that he has a reputation for being an obsessive himself (someone else mentioned stories about him infamously neglecting his family). Sure, he's become very successful at what he does, but overall he shouldn't be throwing rocks at others that work in the medium, especially those primarily producing a very different type of product (TV instead of movies).
