Well no-one said they have to implement it themselves. I'm sure Google and Apple are willing to send a hardware-signed attestation that the device owner is 18+ if required bu the state.

I think this is by design. I think small independent new websites will cease to exist.

I'm generally supportive of bans like this, but I don't want it to come at the expense of the privacy of adult users. I fear this is the way we're going in the west.
