Pillow came off as an underdeveloped crybaby, but some of his points were valid. 8chan existed before Q, and Q basically turned 8chan into 'Qchan', then got 8chan killed outright and the only reason it's successor even exists is because it's unofficially just Qchan.
A lot of the old pre-Q 8channers are still pissed at what became of their community, and what was it all for? So that lonely gen Xers with insomnia can debate whether or not a very clearly bald man was actually an interdimensional Donald Trump wandering around on the White House lawn? If I was pillow, I'd be pissed too.
