Apple iOS now requires age verification to access websites it deems 18+. Not even using another browser like Firefox works, it's blocked at the OS level.
I was putting off switching to Graphene or e/os until prices improve, but looks like my hand is forced.
Edit: VPN doesn't even work because Apple knows your GPS location. I haven't tried location spoofing yet because that's a bit more annoying to setup.
The problem with that is most of the important web pages are owned by the government or oligarchs (is there a difference anymore?) and we all know they're all for this push for de-anonymization.
