Another point is what prevents UK govt or UK bots to sign up for Proton Vpn say themselves and the difference between bots and humans is becoming thin especially for such Private Vpn's and then UK govt comes again knocking asking for age verification.

Honestly makes me feel like UK citizens are hostage in their own countries & we might see more UK IP's being blocked from accessing services because the idea of Virtual private network is still vague in my opinion. One can abstract a sort of VPN on top of xmpp or matrix servers too or even telegram as the intermediate. Would that mean that UK govt would come knocking onto these asking for who created the VPN (suppose I built a VPN which uses telegram to send messages/packets or uses telegram infra, so would they come to telegram asking what is the IP/detail info of my telegram user, would they go to signal or xmpp or matrix providers too? What if I use a provider who colo's on a datacenter and they go to the datacenter asking for access or the company behind datacenter

I am not saying that they would for something so niche but the fact of the matter is that nothing's stopping them from the laws from what I can gather.

They would only have to do it once to instill fear in the masses. I mean technically just this law has instilled fear and I am not even a UK citizen

Someone familiar with UK law please comment on my message but VPN is such a vague term imo. Like at this point you are just targeting private networks or people who meet online in private

VPNs LITERALLY means Virtual "PRIVATE NETWORKS"

What gives the govt right to intercept between two parties communicating in any way (enforcing a condition for one party to have Id of other for age verification etc.)
