MSFT already has tons of competitors' data through OneDrive, O365, Azure, not to mention VSTS... There is literally no way they would breach that trust, not because of any ethical concerns, but because the strength of their brand is that their sales people can call your CIO or CSO and someone will loosen the purse strings and renew your O365 contract for another 3 years. If they destroy that relationship it will basically be the end of microsoft.
We're a place where coders share, stay up-to-date and grow their careers.
