SUSE because of Yast and the (german) company’s rumored?stance on antisemitism

I was really surprised to read about the antisemitism allegation. That's a very serious accusation. I've looked into it and it seems that these claims are controversial. First thing to mention is that the accuser said himself that this was about the company SUSE, and not the distribution openSUSE.

The article claims there are emails and other employees' statements as proof, but provides none. The article is also over a year old, so why hasn't this led to any public statements from SUSE or any legal or other actions? Antisemitism is a serious offense in Germany.

Discussions on reddit and hacker news all state that the writer has gone off the rails. When being called out on reddit for deadnaming a trans woman, he plays dumb. I don't think he's dumb. It seems to me like he's transphobic and acting like a troll about it in good old American conservative fashion.

For me, this seriously calls into question any claims he makes about social justice stuff, even if it concerns himself. He apparently views other people's social justice as something to play with, so my gut feeling is that it would be no concern to him to lie or bend the truth about stuff like this in order to achieve something. It's all a game to him in the political arena, not serious life issues.

If I'm wrong, all he has to do is provide the proof he claims there is, even if only anonymized.
