In most cases those comments weren’t about the service they still running at 40. His comment was also him self-reporting that he shouldn’t be trusted with user data, when his whole business revolves around user data. If it was some off color joke in poor taste, I wouldn’t care so much.

Even if he said something in his role as CEO of Facebook?

"Young people are just smarter" and so on...

I don't disagree with your point, but nothing is absolute. In this case, he's essentially done a tremendously good job of showing us since then that, no, we can't trust him. He's more than lived up to his words.

Thanks for the link, but I can read that, too many intrusive ads. I'll give it a go when I get to a computer.
