Earlier quoted context omitted.
I remember reading somewhere Apple had/has to make AirDrop interoperable due to EU's DMA.
So is Airdrop now less secure or private? I don't trust any standard Google had their hands in.
AirDrop is a peer-to-peer protocol, both the recipient and initiator need to explicitly take action, and even in Apple's implementation provides no authentication (recipient device is chosen by name, which anyone can change in their settings app). There is no way the existence of this Android client would reduce Airdrop security on iOS.
Do you also believe that TLS between an Apple device and a Windows device not secure either, since the Windows device uses a different, non-Apple-sanctioned TLS implementation, and the mere existence of which would somehow weaken Apple's TLS stack?
