I don't think that's accurate to say, really. There's definitely some shows with gay undertones, but the vast majority of their post-2010 catalogue has either no romance or heterosexual romance (Hyouka, Chuunibyou, Tamako Market, Amaburi, Koe no Katachi, the Hibike film, Kyoukai no Kanata, VEG, and so on). Slice-of-life is pretty accurate, though. I don't think it's fair to say that they've changed drastically, either. VEG and their Key adaptations such as Clannad are really not so different in spirit, nor is something like Kobayashi's Dragon Maid really all that different from Lucky Star (which was SoL with heavy gay undertones all the way back in 2007).

The shows that got them famous have implied homosexuality. They also made other stuff, but Hyouka isn't exactly the first thing people think of when talking about KyoAni. Also, Hibike definitely falls into the implied homosexuality category. I've got a friend who only watches it for this reason.

It's true that you can trace their change further back, but at least they did Haruhi until 2010. Since then they completely divorced with their previous fanbase, though. The people liking FMP and Haruhi, who gave them traction in their early years and who were disappointed by KyoAni favoring other types of anime, instead.

I haven't watched Hibike, but to my understanding the tv series has a lot of implied homosexuality while the movie is straightforward heterosexual romance. I also disagree that the shows that got them famous are the ones with homosexuality. They were already plenty famous after Clannad and Haruhi, and Koe no Katachi is at least as high-profile as Free or Maid Dragon. Let's agree to disagree on this one.

Anime fans don't have that long of a memory, because most anime fans drop out of the fandom after three to five years. So while I agree that they were famous for those shows back in those days, it's also a reality that the current generation of fans most likely doesn't even know something like Clannad exists. KyoAni is currently famous for slice-of-life shows with implied homosexuality.

Side question: What's wrong with making money from implied homosexuality?

Thank you for responding to me. That is a viewpoint that I had not considered.

Why do you assume there's something wrong with implied homosexuality, but not with slice-of-life? Both are quite common in anime. Not sure why you would single that one aspect out.
