Why do you complain about that on /a/ of all places?
Let's see what /a/ loves to talk about right now on its first two pages... Yu-gi-oh, Boruto, One Piece, Shingeki no Kyojin, Raildex, Dragon Ball Super, Fate, Franxx, Monogatari.
Of course the industry caters to the consumer tastes. And as long as the average consumer has severe shittaste, they will keep producing this kind of shit.
How can you blame "otakus" when /a/ has some of the worst taste of any anime community?
