The only issue I have with the letter is the spurious inclusion of CP. It has little to do with the substance of the matter. But overall this is a pretty fair letter. As a fact, FB has shifted the focus from themselves as a platform provider onto potential association members. That literally means that regulators, have no choice but to focus their efforts on those member companies. Sure you can take it as a threat, but it really is just a very sobering fact.<p>I think it also shows how little faith these companies have in this tech that they have all just bowed out at the fist sign of (very obviously coming) government push back. If they thought this was really fleshed out and had the kind of earning potential that FB has implied they'd all be doing their best to play both sides for as long as possible.
