Sure … let’s say a typical phone can be unlocked with a face id. So hacking a library of 10 million facial images has some benefit in getting access to a phone (or other device), which in turn causes further dominoes to fall.
For this reason, I would never use biometrics to unlock a phone or anything else, not a face, not a fingerprint, not a retina scan, not a voiceprint - since the more companies use these, the more that data will be public domain aka hacker domain.
Depends only on your government. EU? Yes, they can play hardball and they could achieve that. Australia? Nah, they only do what suits their agenda.
Unless they are forced by the law to reveal what they are doing.
That may depend on your privacy settings. What you post on social media should never be “public” unless you expressly intend for it to be public. However I understand that there are a lot of lamers.
