Always for the same dubious straw men reasons of terrorism and co, they want to control everyone. Like for banks, the excuse is to ensure that no forbidden foreign actor is allowed the use of the service , but just for that the billion legitimate users will all have to provide their complete justificative info, IPs, and support documents to later be used by the org or gov for whatever reason they will want once they will have them.
Like for banks.
Imagine if the same thing was requested in the real world, like forced to prove your identity when you take gas, When you buy a computer, when you buy a condom.
