I don't want to assume bad intent, but I find it hard to believe that someone could be so naive about the project and the organization controlling it.
"should have known" is what most of these comments are talking about. As a thought experiment assume he was lied to, most of these comments are talking about the ignorance and whether it was sincere. Was he this naive or is it easy to be this naive (i.e. self imposed ignorance) when there's a deal to be made.
Now that it has proven out as people expected, they're calling him out on it again. Perhaps other people will learn a lesson from it? I can hope.
Carmack also wanted to sell because he had built businesses before and wanted to focus on the technology without having to deal with survival.
It wouldn't surprise me if Luckey believed that would be the outcome. I think Zuck's strategy as CEO was also less clear then. Today it would be obvious, back then though, I'm not so sure.
I think Facebooks business strategy how to make money was pretty clear at that time as well. Just remember the [Facebook Home](https://en.wikipedia.org/wiki/Facebook_Home) Android launcher that allowed the company unprecedented access to the data on the device. https://gigaom.com/2013/04/04/why-facebook-home-bothers-me-i...
The one whose business idea it is to lock up all the world's information?
The one that, together with Quora and Instagram, shove a login screen in your face when you haplessly click the wrong link? When all you really wanted some some local business opening hours or contact information?
The one that already owns your contact information, and aren't afraid to tell you so, because they tricked any one of your friends into letting their app suck their contact book dry?

Let's be real, the reason he was wilfully naive is because they send him a big fat check, just like they did to the Whatsapp founders, in the same year I think.
I just wish they would at least be honest and say it instead of this whole "I thought our dreams would come true" talk.
Step 1: They get an credible offer for a ton of money.
Step 2: Their brain starts to spiral out of control and can't stop imagining all of the things they can do for themselves, their family, their friends, the world, etc
Step 3: They've just created millions of incentives for themselves.
It takes a very strong person to drive out the biases that money creates in our brains. Monetary incentives are the strongest bias creators, beaten (probably) only by sex and blood (i.e. family relations). Breaking them is the work of an iron will. You had better assume you'd do no better.
Let's not assume bad intent and recognize the reality that things change. That any corporate statement or policy is not true in perpetuity. It's very possible that at the time FB really did believe it. It has been 6 years since the acquisition after all.
