This is creating more harm to its users, creating more opportunities for scammers, and also creating more chances for losing one asset. From my greatest understand and knowledge social media platform is one of the common places to scam people. Reason being that, no ones monitor's your chat and to what discussion and business deal they had. There are lots people who impersonates influential people on social media and coupled with Elon Musk issuing out blue-check marks to any accounts without being the previous way of operation has made it very common for scammer to flood into the platform.
Enabling payment system is like a great opportunities for those people to swiftly carry out business deal without having an external body knows about their transactions for example like banks, most at times bankers have saved lots of life's from losing their hard earn money from scammers by which clients going to banks to make payment, bankers always questions their transaction and to know what business deal that brought up this huge transaction and immediately they mentioned twitter or Facebook or IG payment they stop them no to make such payment that it is a fraudulent business deal.
So to me I don't see it to be a good news or good opportunities to its users.
