Facebook's "apology" is nothing but a cynical attempt to stem public anger...the kind of anger that might cause governments to act against it.
Until an aggrieved party can access an appeal process in a reasonable time and get ridiculous situations like this taken care of promptly, Facebook remains an irresponsible gate-keeper, and its apology remains a fraud.
We'll leave for another day the fact that Facebook is inflicting its prissy, Puritanical standards on the rest of the world. And no, the argument that "you can always stop using it" doesn't apply. It has occupied its niche in the internet's ecology completely, leaving no reasonable alternative. Practically speaking, it is a monopoly.
