It is true that writing to the board will get you noticed, and that you might not like the consequences. If you value having the job then don’t write to the board. Even if you are right, being noticed like that isn’t going to endear you to your boss.
But if you care more about doing the right thing then writing to the board is the right thing to do. And after a few years of working at Microsoft you might not value your job very much either and you too might decide to go out in style.
