The fundamental problem here is that they have a billion users and most of them don't know what they're talking about. If you create a simple way to contact the company it will soon be full of messages from end users who can't even articulate what their problem is but it's usually some kind of malware or user error and is definitely not a problem with whatever component they're reporting the issue against.
What you really need is a way to report problems which is high friction. You have to submit a git pull request of your ssh public key so you can transmit your bug report via sftp. Now they only get bug reports from people who can figure out how to do that and can actually pay attention to them because it filters out all the spam from people asking Microsoft how to connect their Android to a Mac.
