Legally speaking F-Droid can do a lot of things, but the law has no bearing on the discussion of whether it was the right thing to do, if it will help with FOSS adoption or finally if they are somehow absolved from criticism for their inconsistent and politically biased policy enforcement.

I see no reason why we should restrict FOSS adoption to only people within an arbitrary and unrelated political sphere. Everyone wins when everyone is using FOSS, even the people we don't like. Unfortunately F-Droids decision on this matter hurts FOSS adoption from conservatives who will only continue to associate FOSS with the left-wing.
