IE like Crypto AG:
In 2020, it was revealed that the Swiss company, Crypto AG, which provided secure communications services to ~120 governments throughout the 20th century, was secretly ran by the CIA and West German Intelligence. The CIA and later NSA were able to read encrypted communications for many countries such as Saudi Arabia, Iran, Italy, Indonesia, Iraq, Libya, Jordan and South Korea.
I know your example is the opposite, but any service that is run and hosted in the US.
It’s one of the major issues with Signal.
Not to mention Graphite and Pegasus, Israeli spyware.
You got that right.
