Bitcoin isn't created for advanced Smart contracts. It is quite simplistic to improve security and the proposal would be limited if it would be based on the Bitcoin underlying protocol and would introduce vulnerabilities like Ethereum in the Bitcoin Blockchain if such complex Dapps are introduced.

Well my biggest point is, it seems it would be reliant on a Social media like X and meta
This would make its decentralized system you have portrayed centralized.
And I definitely don't trust any Social media platform with privacy.
