"It's a mistake." OK, you could be right.

"Needs to stop." OK, you could be right on that one too. I don't think you are, but that's not the point.

Neither of those adds up to "it's currently illegal". (Whether it's actually illegal probably depends on the details of how he did what he did.)

Further, neither of those things adds up to "the howling mob should attack him until he stops". (Even if the "attacks" are purely online.) I am against "attack him with outrage dialed all the way up to 11 without actually understanding what his tool is and does". I am also against giving in to the outrage - it just shows the mob that baseless outrage attacks work.

You think it needs to stop? Fine. Persuade him that it needs to stop, and therefore that he should stop. Convince him - not with a mob screaming in outrage, but with reason.
