Like the millions of "terms of use" breached by the exact trillion dollar companies pushing for passkeys (Google, Microsoft) while training their AI models? Sounds like terms of use are entirely irrelevant in the first place.
Then see what happens if meta downloads an entire library and trains their AI with it.
Meta just figured the fine is worth the leap ahead in AI training, and I kind of agree.
Since when "you are not supposed to do it" works? :) Most videogames cannot be freely copied or modified/tampered with, according to their ToS; still, companies implement draconian DRMs/anticheat to block people from doing it anyway. This is the same situation.
I mean, it was an example. Replace it with an amazon account and the argument remains the same.
I doubt streaming services are looking to make passkeys the only way to authenticate devices though. Too much competition, and too many valid use cases for use outside of a personal device.
