The good guys have a non-transparent approval mechanism for permission which no one can audit. In reality, you have no basis for claiming it's an effective overall control mechanism because none of us can see most of the data. Further, there have been numerous documented cases of abuse like intelligence officials spying on their significant others, parallel reconstruction on cases where secret data shouldn't have been used, etc.
An administrative policy control where application of the control is handled by the people holding the data with 0 auditing by anyone outside the system is not a strict control. Do I trust American intelligence more than the Chinese government or Huawei? Definitely, but that does not let American intelligence off the hook or justify what they are doing with mass data collection.
