Which company’s devices are you using if you are skeptical of your ideas/data being stolen or misused by the respective company? do you also worry that you may be secretively spied on? Which mobile device, laptop and cloud do you have for personal use? Is Apple ethically better?
Microsoft has a government cloud and you can get g1/g3/g5 licenses. If its secure enough for the US government for top secret clearances then not much to worry about.
Nothing on the internet is “secure enough for the US government for top secret clearances.” Not even secret, for that matter. Only traffic classified as confidential traverses the public internet. Everything secret and above traverses a network which is entirely physically separate from the internet, meaning an internal network of government owned network devices which don’t touch the public internet at all. I can tell you this from experience.
