The prospect of making money does strange things to people's perception. PG knows damn well that is garbage that provides no value (rather, negative value) to the user and just pollutes society's computers. There is no way he would defend it under normal circumstances. Who would? Good job YC, you're the new Bonzi Buddy, the PC cancer. I can't wait to clean that shit out of my elderly relatives computers when they complain of sluggishness, crashes, and intrusive ads, like the good old days.
"The users choose to install these things."
GMAB, you know better.
