I think it is quite different though, in that biometric-as-a-device-authenticator features keep your biometric data on your device. The plan with worldcoin is to create a central database of this data.
Supposedly Worldcoin deletes your biometric data after it's done generating a hash of it. If you don't believe that, then why would you believe that Google and Apple don't secretly send your fingerprints and facial scans off device?
For one, those entities operate in the US, and are subject to US law - it may not be great at times, but that's a start.
Worldcoin on the other hand went to the third world and went through Africa offering people almost a month's wages to give up their biometrics. That, to me, should merit a deeper dive into what they are doing and why.
