Let's see:
- judged by angry mob -- yes,
- no ability to defend oneself -- yes,
- killed -- no (though seeing polarization and level of anger here it's possible that he'll be eventually physically assulted),
- person demolished, life ruined -- yes (Stallman got removed from the org he created, got fired from his work. Another poster here written that his friend got accused, defended in court with hard evidence, life is still ruined).
Comparison with lynching seems fair to me.
All of this got me thinking about creating, you know, accepting tech community where everyone is free to express their own opinions. I'm personally fine with my code being called shit and me being called dumbass for a good measure, just tell me what you really think and we'll sort things out faster instead sugar-coating stuff to not hurt my ego.
