This is clearly not “a russian wondering what’s wrong”, this is “a russian living in russia who doesn’t want to die in prison”. This would be a fair criticism if there wasn’t a law criminalizing pacifism together with many laws making it easy to deanonymize internet users.
Silence does not fix things.
Neither does grandstanding on Lemmy. It especially wouldn’t fix anything if a person in Russia trying to build international relations would go to prison for it.
Actually, that would make it non-free (a.k.a source-available) software by FSF’s definition. You can do something like Qt (copyleft license for free, permissive license for a fee), but this doesn’t really work for a lot of software.
