This is the MVP comment.

When you have a carpenter visiting you don't announce they can go into your kids' rooms (for reasons unrelated to the job is) and what not -- the [default] contract is they're there to do a job and their privileges go only as far as the job requires, they normally also ask you first time where your toilet is, although we all agree they can use it. It's a contract, formally and less so, and things work when the contract is abided by. The carpenter also can't say they had the right to the cookie jar on your kitchen counter just because they were working there.

By not implementing such a contract with code, Microsoft has shown negligence. And they have had _decades_, so it's likely a "business decision".
