This question of who gets to see your company data is I think a lot more thorny these days than ever before.

You're joking about email, but that's of course the reason why companies will pay a lot to host email on premise instead of relying on cheaper offsite solutions. I think Exchange Server is Microsoft's biggest foot in the door to access conpanies tbat otherwise wouldn't care much about the other Microsoft services.

Having a third party look at every email you're sending around is just a non starter for many businesses.

Getting the same setting in an editor where your code is shared with the editor company everytime you want to show it to a colleague is not trivial at all.
