The USA partnered with the German company, Siemens, to install hidden wiretaps into the phone equipment that was used by every embassy in the world. For years the USA had access to literally everything that ambassadors from every country were saying.
Then we have the USA Congress holding a trial after it was revealed that every telecom company in the country broke the law and spied on all internet traffic and gave it to the NSA. The result of that trial? Retroactive immunity for all involved and changes to the law to make it legal going forward.
Then we have the Snowden leaks that show the NSA has chosen “market solutions” for data gathering, meaning that they will collaborate with private companies, even funding them through the network of money, so that those private companies gather as much data as they can on citizens so the NSA can buy it. They also have major partnerships to install persistent vulnerabilities that they can exploit, and there are major revelations in the leaks about how they influence which companies but which companies in order to ensure control over the startup tech that doesn’t collaborate with military intelligence.
Prism, Raptor, Echelon - these are the programs we know about. There are undoubtedly a number we don’t.
Then you have Oracle, Palantir, AT&T, Verizon and many other tech companies that were either founded by, funded by, or wrre revealed to be infiltrated by military intelligence.
Military intelligence influences cryptography at the highest levels, pushing for specific algorithms to be adopted by ANSI and ISO as the default recommendations.
USA spies get jobs in American tech companies. That’s part of the program. High level State Department and Military Intelligence officials take executive jobs openly in companies like Facebook, Twitter, and Google.
And then they lie about it, have been lying about for decades, and create clear and obvious propaganda that belies their motivations. When TikTok was being accused of being Chinese spy tech, the USA forced TikTok to give control of its USA operations to a USA tech company with executives and staff from the USA State Department and Military Intelligence. Even after this happened, they continued to publish scare articles about TikTok being Chinese spyware even though in the USA it was controlled entirely by the government.
The USA has 600+ military bases around the world, it has secret black sites in dozens of countries where it conducts torture, bio experiments, and illegal operations explicitly to avoid legal troubles in the USA (because they aren’t there) and legal troubles in their host country (because they have immunity).
