I think it is time we started putting the US government into more mainstream cybersecurity threat models.
"The Executive Order of October 7, 2022 (Enhancing Safeguards for United States Signals Intelligence Activities), establishes enhanced safeguards for United States signals intelligence activities that supersede the safeguards for personal information collected through signals intelligence established by Presidential Policy Directive 28 of January 17, 2014 (Signals Intelligence Activities) (PPD-28)." - Essentially stating that your rights mean nothing to them.
The US government has essentially just opened the flood gates that much wider for infringements on the rights of their citizens. Even if this does not actually alter the behind-the-scenes activity that the government has undoubtedly been partaking in, it will still allow them to more openly call forth the data collected from these clandestine activities for more mainstream purposes, and before you say that they would be sued for this: "This memorandum is not intended to, and does not, create any right or benefit, substantive or procedural, enforceable at law or in equity by any party against the United States, its departments, agencies, or entities, its officers, employees, or agents, or any other person."
There is too much to cover in just one post, and I highly recommend you read the links, but the TLDR is that the US government has just shaken off the vast majority of the restrictions it had on SIGINT.
