I would be dollars to doughnuts that the author of that site and the editors of that "wiki" have made or thought worse things at some point, but because they have not reached a certain level of celebrity, there's no dossier on them. It's truly ridiculous to me the amount of effort spent on trying to claw others down.
I accept that inequality exists and perhaps RMS has some awful opinions, but if that's the case then just ignore him.
If there are people who are choosing to make it incumbent upon themselves to take down these "problematic" individuals, then it must be because they think that all of the systems that have allowed a person to continue to exist despite those opinions must be unreliable in adequately judging them. If that's the case, then wouldn't it be more practical to fix the endemic problem rather than destroy a single person? I'm guessing that the latter is just easier to do and more profitable as well. You gain "credibility" by attacking someone else, so it's difficult to believe that they are doing it for altruistic means.
All in all, I'm pretty sick of this nonsense. A world where everyone is constantly being watched by eachother and reported on is already too authoritarian for me to want to continue living in, not to mention the already authoritarian governments doing the same.
