Thank you for this article. It shows exactly what's Facebook's plan. They will join in, make their own implementation that doesn't work well, pass the blame to the other platforms that use the protocol*, which in turn pressures them to debug and slow down themselves around Facebook's stuff, and then they cut them off entirely.

The correct attitude is to extinguish Facebook now. They're not welcome.

*And yes, this would work. Users are absolutely gullible about this shit, even without ever being told anything directly. Look at Apple users and their blue/green speech bubble thing. Every single flaw with the system is Apple's fault - but the dumbass cultminded users see the green speechbubble and blame the other users for the flaws, not Apple. They literally just did the stupid tribalism comic and it worked.
