Well - looks like I figured this out the hard way.

BTW, there is absolutely no connection between a legal license and DRM stuff. The DRM stuff, even the fact that there is a license key, is not even mentioned in the license. It also does not say anywhere that when I have two licenses, that I have to use two different license keys on installation.

They are separate topics. DRM restrictions will have no effect in court, except perhaps when they violate "fair use".

So, concerning your point about Illwinter does not need to care: I am having problems with a part of the software that is not properly documented and leads to faulty behaviour. So, asking for documentation and suggesting UI improvements by asking for proper error messages is not absurd.

I can understand and accept that Illwinter introduces DRM stuff (though I do not like it, because it restricts what I can do with the software). But then making it behave somewhat nicer would be great.
