I was referring to the Snowden leaks
https://www.theguardian.com/world/2013/jun/06/us-tech-giants-nsa-data
And how a lot of it can seem far-fetched and conspiratorial at first glance
Just to sketch a brief outline, Snowden worked as a government contractor for the NSA who went on to leak the NSA’s overreaching surveillance programs, one named PRISM which collected data from tech and communication companies. Although they didn’t create “backdoors” in the traditional sense, the program created a more streamlined system to funnel data back to the NSA, following whatever broad guidelines the NSA used to determine whose data should be obtained; with little to no oversight
I didn’t bring it up to raise paranoia, but to reecho the sound advice of exercising a healthy dose of caution and skepticism regarding big tech (or any tech) and the government, because honestly we can never know for sure, especially since the government has little inclination to respect our right to privacy and the Fourth Amendment
