The easiest way round this UK authoritarian nonsense would be if Mindgeek et al immediately replaced all media requests to their CDN from UK IPs with a list and photos of the politicians behind the continuous erosion of digital freedoms. The entire country would switch to VPNs so fast, the GCHQ would flip out.
That is true, they will try whatever is needed to keep the UK market as UK eyeballs are worth more than other places.
It’s more like a required gate, like if the UK pushed it, I doubt we would see gates in other jurisdictions. It’s all very chilling effective. I don’t think it’s so much as a gain (why would you even gate it unless regulators were threatening IP and hostname blocks).
