I can certainly see that. The mid-00s was when my anime consumption took a nosedive, and that wasn't just the decline in the 'boom.' For one thing, I stopped being a teen and became (something of) an adult, and it seemed shows were getting more and more of a laser focus on targeting a teen audience. This also includes a sort of teenage view on sexuality and titillation, which becomes creepy to any non-teen watching. I feel like anime is in a place not dissimilar from the worst eras of mainstream Marvel/DC comics in the past couple of decades; with stories impenetrable to non-readers and a solidification of style that suggested artists who only know writing a drawing from what they've seen in other superhero comics.
