While I don't agree with OP... you could make a case that switching to Git is a way for Microsoft to make itself more fashionable to the engineering community at large.

The marketing here is: it's cool to work at Microsoft again!

But that makes it a technical decision! If it's easier to attract talented engineers because you're using git, that improves the product. I was trying to make this point in my other comment too: OP is drawing a sharp line between "marketing decisions" and "engineering decisions" and sneering at the former, but actually the boundary can be pretty fuzzy.
