Sure, and tech companies in USA are super trusted. And for sure no backdoors are found. Just one of the recent examples when author of Telegram was "contacted" by USA government during his visit to USA. If you really want to be honest - you should understand that every government is interesting in "access" to popular tech tools - laptops, phones, social networks, messengers and etc.

And it will be really good also to check facts and not yellow press like CNN, BBC and etc and just bullshit Russia.

Trust is a weakness... Never forget it :)

Yes. And NSA/GCHQ just doesn't involve itself with any tech companies in the U.S and EU respectively.

What is IntelME or AMD PSP just for starters? This is completely untenable in the face of all the revelations starting with Snowden, nsl letters, secret processes and secret courts.

No one will seriously claim the US tech industry has not benefited from the government.

No point singling out specific governments, the NSA is not on your side.

>I would stay away from proprietary software, especially if it was written in Russia or China.

Why? What have you found in proprietary software written in China and Russia?
