Bit surprising that as a German you'd regard antipathy for Nazi tropes as "political correctness".
It is surprising to me that one suggests to choose software on the political views of the authors and not on technical considerations.
This has nothing to do with me being German nor did I support or endorse those (admittedly strange) views. All I'm saying is that it has nothing to do with their software.
Actively contributing or joining a group would be an indication that you share views with them.
But having installed a piece of software maybe through a package manager? Simply using it?
That was my whole point.
Also, for the rest, I totally agree with you.
