I think this will have a number of consequences:
Many people will seriously restrict their use of cloud resources. I would never put any critical data in a cloud space.
Those involved in clandestine activities will use VPNs and encrypted peer-to-peer messaging apps like
bleep and the authorities will have no data to pursue. This has the exact opposite effect to that which it is intended. When you
know that you'll be snooped on you take precautions
It will be abused by all the authorities in the OP's list.
