" Imposing regulation on Facebook will not make people jump ship"
Nor this is the aim of any regulation. Unless you demonstrate that Facebook is so toxic it has to be forbidden (maybe easier than many think).
But that doesn't mean Facebook can't be regulated, and it can hoard and use user data as it likes.
Thanks to any divinity no supplier or customer of mine thinks Facebook is a way to keep B2B contacts... friends know how to contact me without using FB, so, yes, there are no-Facebook options, dear Zuck....
