Not inherently, but I’ve been in communities where everyone is weirdly positive in the name of being “non-toxic” and it resulted in people generally not voicing dissenting opinions, which is pretty similar to an echo chamber.
I no longer frequent those places because it all felt a bit artificially happy like a kids TV show.
I think it’s to give the top women a platform, for young girls to see people like them on the TV and make them believe they can do it too. If enough young girls start playing and keep playing, there should be plenty of female players that can compete with the best men in short order. There are also women’s titles that have lower requirements than men’s. It’s a pretty controversial thing; some women refuse to take the “lesser” WGM title over the open IM title.
I’m not saying this works or I agree with it, but that’s the thinking.
