closed source → no control or ability to introspect what it is doing → program instructs your computer to do things someone else made it do
it's not real-time control, but still control (can be real-time with backdoors and related things)
i don't see how you can assert that they do not have a backdoor, maybe they do, maybe they don't, but that's not the point
how are you not uncomfortable with running third-party executables on your machine without having any way to inspect them, let alone control them?
that's a licensing issue, you're talking about free as in freedom software, which is hard to sell
open source software can be commercial, it's the license that dictates whether it will be hard to sell or not
Back door viruses (or malicious software running backdoors) are illegal, and microsoft could be sued by millions of people for stealing their data, Windows also wouldn't have as much users as it has.
I am very comfortable with running my drivers on my NVidia graphics card, I am comfortable with running games like Battlefield or programs like Photoshop or Foobar. If you don't trust microsoft and their closed source software then please dont spam random threads with lies and bullstuff you read on the most random site ever.
Keep it to yourself or ask somebody if it's true (in this case it's not)
