MS shouldn't be allowed to change my default choices they are trying to force people to use their bloatware. Sure most can change it back themselves, but we shouldn't have to, and some will not be able to figure out how to change it themselves. Yes there are people that won't be able to figure it out (e.g. the tea baggers, fox "news" watchers).
What alternative do you want? State agencies dictating how Microsoft can write their own software? How about talking about OSX, and how you literally have no power over that
at all?
In the end, its Microsofts software, you chose to use it, and that means putting up with whatever they want to do with it. The 2000 antitrust case was about monopolistic power on the x86 platform, which is still a valid argument, but has nothing to do with whatever defaults or settings Microsoft wants to put in their OS.
If their TOS said we are going to record your microphone and webcam and sell all that footage to whoever wants it, and you click yes (and you would have to to use the OS) there is no violation of anything happening because you agreed to be spied on. That is how a lot of this Cortana stuff works in the first place.
You chose your OS, and you have the choice to either not use Windows 10 or any MS OS at all if you wish it. It might even be a hard choice, if you are dependent on Windows only software, but its still your decision to make, especially if you decided to use Windows-only products in the first place.
