Genuinely unclear why Twitter wouldn't be setting up fiat currency tipping first. If much smaller operations can set up creator funds/tipping, is there a reason Twitter seems so hesitant?
My understanding is that this is just another provider being added to their existing tip jar [0] feature. They essentially let twitter users link out to their third party cash app, paypal, venmo, etc accounts, and people can use those third party services.
This is really no different - they are linking out to Strike, a custodial lightning wallet.
