My Android phone prevents me from recording phone calls at the request of my carrier, even though it's totally legal for me to do so in my jurisdiction.
I'm not loving where this is all going.
Luckily there are alternatives in the form of code displays and NFC chips. However, next year I won't be able to watch porn unless I verify my age using a smartphone, no alternatives are planned. Or rather, I have the "free choice" to choose between a privacy preserving ZKP solution operating in the kingdom of Google or uploading my face to a porn site.
Dark times.
Also, this isn't just about porn. For example, I can barely use Reddit now if I connect with a UK IP address: the merest hint that there might be some NSFW angle to a post is enough to trigger their algorithm into requiring age verification.
