I don't mind the reason being "the right reason" or not, getting rid of Microsoft will be a net-positive regardless.

And it's a process that will take years, and be step-by-step, you can't just "torn out and replace everything" in one go, not to mention how bad of an idea that would be regardless.

I'm happy we continue to do this step by step, making sure it's working alright and is the right thing along the way.
