He is some sort of a sociopath. I remember having the same feelings reading his Blogposts. But after rethinking and checking the facts it came to me how awful his own reaction was.

If you use an infrastructure as the project did, the host is allowed to define rules. In his reaction everything was framed like she as a woman would just fire against his project because of she likes to have power. The mailing list told a totally different story. After I realised his framing was again hateful and misleading, I stepped away from the project and till now all news about that.

The development of a dedicated backend is most probably because of technical reasons since wlroots caused some problems, though.
