Welcome to the free market. It requires open information for everyone, which includes criticisms. As long as it's true or obviously a hilarious joke or parody, he's totally allowed to say it. And, doing that benefits everyone else because the market can adapt.
Then again you're trolling so this comment is more for everyone else than for dipshits like you.
I like how you say "as long as it's true or obviously a hilarious joke or parody".
It's like, it's not enough to be obviously a joke or parody, your standard requires actual hilarity.
I can see you in the judge's chair: "I'm sorry, it's obviously a parody but I just don't see it as all that funny." "But your honor! [explains joke]." "Oh. Hahaha, okay, I missed that. Haha, that's pretty funny. All right, counsel, case dismissed!"
Pay me when I'm owed and you won't get criticized for not paying me. I'm simply saying what happened: if they didn't want to have it talked about, they shouldn't have let it happen.
Don't do business with mikeash because he will totally criticize you on the main page of Hacker News.
