Hi Doinik, I'm the Lutris Maintainer for Debian, and I completely agree with you. However, at least for Lutris, there is no choice since we recommend winetricks. Thus, I simply copied the copyright comment from winetricks.
For winetricks it is a bit more tricky as it can download non-free dlls afaik. On the other hand, Lutris downloads tons of files as part of the runtime, and there might be non-free files in there (I'm aware of at least one icon that has an unknown origin). In both cases, nothing is installed system-wide, so one could argue it's more like automatically wget-ing files to your home directory. There was a larger discussion about this on debian-devel-games [1], you might be interested in that. Regards, Stephan [1] https://lists.debian.org/debian-devel-games/2021/01/msg00013.html
