-japan's economy fell apart in 1991, animation quality fell off a cliff
-cgi happened, making anime look even worse (don't get me started on AI...)
-OVAs don't really get made anymore so all TV anime has to conform to strict broadcast standards
-there was a famous serial killer dubbed "the otaku killer". They found anime in his apartment and so there was a massive moral panic against anime in japan. Anime from that point on changed drastically.
-spirited away put the nail in the coffin in 2001. Now every anime film is trying to be a "prestige" movie for little girls, with themes focusing on romance, coming of age, and gender roles (see every film by modern anime directors such as makoto shinkai and mamoru hosoda etc)
