I know a lot of time passed by, but I am not sure if the rejection reason
for lutris was factually correct. And the uploader didn't follow up with
that.
I tested recent deb packages and sources of upstream lutris, including git
versions, and there are no non-free components in source, used during build
or in binary package.
I also launched and use lutris, and it did not download or used any non
free components.
The fact that lutris can be used with non free software, isn't any
different than apt or wget can be used with non free software.
It definitively classifies into 'main'. Not 'contrib'.
The only (fixable) issue is that binary package depends on 'unrar', which
is non-free, and packages in main afaik can't depend on non-free ones with
alternatives. It should instead use Recommends, or use Depends: unrar-free
| unrar, or just unrar-free should suffice probably.
PS. It is obviously possible that in 2014, situation was different.
Best regards,
