We can't weigh the positive impact a person has had against the unrealised potential for positive impact from all those they forced out of the community. We just don't know if Stallman is a net-positive because we'll never get to see the alternative case.

Given this, we can't use an "end justify the means" argument, which means we have to hold people accountable in isolation from any positive impact they may have had.
