Meta are performing what is called an EEE attack (Embrace, Extend, Extinguish). Basically, it involves a larger corporation creating a thing that hooks into an open standard, artificially inflating it, slowly adding new, proprietary closed-source features that other members of the open standard cannot use, and eventually removing support for the open standard entirely, forcing other users to enter their walled garden because that's where all the people are. https://en.wikipedia.org/wiki/Embrace,_extend,_and_extinguish
