Everything that hits American streaming services with an English dub (netflix, hulu, hbo) will attract shittier fans because there's less gatekeeping.
When you have to torrent a fansub every week to keep up with a show, you only have fans who care enough about the medium to actually do that.
With these the audience ceases to be "anime fans" and instead becomes largely zoomers and women who want background noise while they browse their phone.
