In the '70s, if you were into computers you were most likely also a fan of Star Trek. I remember an anecdote from the 1990s when an entire dial-up ISP was troubleshooting its modem pools because there were zero people connected and they assumed there was an outage. The outage happened to occur exactly while that week's episode of X-Files was airing in their time zone. Just as the credits rolled, all modems suddenly lit up as people connected to IRC and Usenet to chat about the episode. In ~1994 close to 100% of residential internet users also happened to follow X-Files on linear television. There was essentially a 1:1 overlap between computer nerds and sci-fi nerds.
Today's analog seems to be that almost all nerds love anime and Andy Weir books and some of us feel a bit alienated by that.
Especially because (from my observation) modern "nerds" who enjoy anime seem to relish at bringing it (and various sex-related things) up at inappropriate times and are generally emotionally immature.
It's quite refreshing seeing that other people have similar lines of thinking and that I'm not alone in feeling somewhat alienated.
Eg if the nerd community had $x$ people in the star trek days, now there are more than $x$ nerds who like anime and more than $x$ nerds who dislike it. And the total size is much bigger than both.
This sounds more as though you actively dislike anime than merely not seeing the appeal or being "ignorant". If you were to ignore it, there wouldn't be an issue...
I don't get the impression that it's meant to be annoying, but a personal preference. I can't know that, though whitelabeling is a common thing people pay for without the original brand having made their logo extra ugly
