I fully agree with you. I'm absolute skeptic about anything Facebook and Twitter and other multi-billion dollar tech companies support. Especially because, the whole project of a decentralized social network, if this succeeded, and really became mainstream, these same companies would loose A LOT of power.

It would be easier to compete with them, they would lose their role as being the gate keeper of acceptable debate on a huge part of the internet, so there's a huge down scepticism from my part, thinking "they will find some way to taint and contaminate this whole project... somehow". Twitter would never actually embrace this idea, certainly voluntarily.
