Good grief people - It's satire. The entire thing is meant to be funny. I didn't even think it was particularly subtle so I'm not sure how others are seeing it any other way.
Pretty obvious only an idiot would write up this rant on his personal blog while still employed at FB. I ignored the content immediately after realizing this. Click bait title. Lame.
He had me until the second point's header. Overall it was a fantastic read if just for the moment of realization. Still it would have benefited with more subtly or fewer items. Some point's like #4 had great potential but needed less sarcasm.
