You use Android by Google and you worry about Microsoft?

Honestly, I think Microsoft or any large company on FCC's radar and media's radar is better option than some company in a distant country.

I'm in Europe, the US is a more distant country than UK, both from a geographical and legal point of view.

Plus there's NSA and shady government practices in US (even though UK is probably sharing whatever they can with the NSA).

Yes, as a person from UK you should absolutely be worried about US government's shady and unethical practices and put pressure on your government to pass various laws that would protect you.

And how has being on the FCC's radar stopped Microsoft from their unethical spying and total lack of concern for people's privacy? (mainly via Win10)
