Or they just operate outside of UK jurisdiction, in which case they can politely decline. Any executives/directors of said company might be liable to arrest if they decide to vacation in uk, though.
The UK already has ISP's blocking sites. Anyone that ignores the law will be blocked, will be interesting to see what happens if they end up blocking one of the cloud megascalers.
Hilarious that they think they can prevent motivated people from accessing information using technical measures. China has been working on this for decades. It's a lost battle. Shadowsocks, V2Ray, xray; protocols like vmess, vless, trojan, etc.
The British government, for all their effort (London has a higher geographic density of CCTV than Beijing) is wasting their time competing for the gold medal at International Totalitarianism Olympics, even the the world's current undisputed champion is losing the internet censorship battle, and always has.
Central planning doesn't work and it never has. That includes central planning of what your citizens are allowed to see, hear, think, and feel.
Depends on the how you formulate the goal in the totalitarianism olympics. The goal of totalitarian regimes is not really to completely prevent the flow of information to motivated people. It simply needs to raise the motivation bar high enough so that all but the select few is fed only government-approved propaganda. The few that retain access is tolerated as long as they don't raise a stink. In this view, the efforts of China or Iran is fairly successful.
The UK has a different flavor of authoritarianism centered on surveillance to (ineffectively) improve "safety", and general paternalism at all levels. It doesn't really intend to prevent the flow of information all that much.
