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).

Compare that to China.

Do you really need to ask why you shouldn't trust the countries responsible for the vast majority of neocolonialism, and the ones currently supporting a genocide?

Just look up some of the numerous shit the CIA has done, or the fact that they collect information on every US citizen to use against them, etc. Like the 1965 Indonesian massacre of 700k to 1mil people where the CIA supplied the military dictatorship with information on them.

From my point of view, Western powers are more realistically gonna impinge on my human rights than Beijing is.

Your circumstances may be different.

Because while there are only obtuse and vague accusations that China is backdooring technology, there's no proof besides a Chinese law that says Chinese tech companies have to help authorities.

The US on the other hand was caught red handed doing what they accuse China of with the Prism system. It was caught spying on Angela Merkle. And just ask Snowdon how he feels about living in exile in Russia for exposing that.
