No, he didn't.
He expressed an opinion as single individual person, he didn't ask for support or rioting against someone or something.
And he didn't ask for nobody to be fired in the first place.
> and that's why people are pissed at him
No, they are pissed because people suck.
They've been also pissed at Terry Davis, another troubled man (more troubled than RMS for sure), that didn't harm anybody in his life, except himself.
