So, I'd start off with OAuth and OpenID Connect as good standards Facebook had been a part of.
Open Graph Protocol (OGP) has been great for marking up web page metadata, also.
In Open Source software, React is an example of a spectacularly successful project hosted by Meta.
To bounce it back, do you have some good examples of open standards that Meta has participated in and ruined?
