Yeah just interpret 3000+ pages of policy documents and if you screw it up, OFCOM can fine you 18 million pounds and hold you criminally liable. Their "simple guide" is 70 pages long and has numerous links to additional policy documents that have more details on how to interpret the law. Any sane company is going to hire UK legal counsel to deal with this, which is easily going to cost five or six figures. And that doesn't include the cost of adding additional technical mitigations to justify a lower risk assessment, or the ongoing compliance cost for services that aren't low-risk. So the rational move for any company that has minimal UK revenue is to just IP ban the country, like Iran or North Korea.
