> Now this dumb announcement comes out that a 3rd party has (apparently legally) established interop with a Meta property with (I am guessing) a completely proprietary, undocumented, secret protocol underneath.

Resd the article - this isn't a proprietary secret API, it's the official intended interop API the EU now obliges them to provide. Not exactly 100% what you're asking for (I too would prefer common standards) but forcing interop access is a very good start.
