You have rushed to make assumptions and judgments here and then insulted the OP. I don't understand why you felt the need to make a personal attack. It's unwarranted. The OP had some nice, encouraging words for the FB Purity guy and then here you go making disparaging remarks.
Although you might not agree with his point, there's no need to say "Not true" and then insult him.
He can simply continue his project in any way he likes. He doesnt need a facebook account to do so.
If he likes, he could also sue facebook for access. But as I said in another comment, I dont know US law enough to know if he would win.
As I understand it, he has a large userbase. So his project has a purpose. Just because its free, it doesnt mean its no good.
