This happens to most things I like. I really liked JoJo's Bizarre adventure when the anime was first coming out and I read all the manga and then when part 3 got super popular the fandom became completely insufferable to the point where I was stopped recommending the show or keeping up with any updates. I have also been really into AI/language models/machine image generation for years before ChatGPT exploded and now "being into AI" usually means "Exporting rational thought to a chatbot." I also feel like reddit is like this.
