No he hasn't.
What he was doing was setting up exposure for Bitcoin entrepreneurs.
If you check the #bitcoin twitter channel, it's chock full of promotions for any and every bitcoin initiative that's going. A lot of them are very interesting too - stuff that you would never know about otherwise.
He's trying to rotate the bitcoin "iceberg" - the stuff that's still underwater.
What would you that he rather do ? Tell you that you were all going to be millionaires or do the hard grafting to make you millionaires ?
He doesn't deserve criticism, he deserves praise for this. Us people are sitting on our hands waiting for our investments to make us rich while he's out there thinking up creative ways to light a fire under projects that will garner adoption.
The joke's on us. Guerbuez has done more groundwork to promote bitcoin in the last 10 minutes than this thread has done in 2 days.

He's made his living (jailed) off deceptive social media click bait to promote penis enlargement pills and weight loss supplements (which, apparently, he himself needs).
So no.
He doesn't deserve praise. He deserves to have his internet priviledges revoked for life.
