Marketing concerns by whom? The nonexisting company behind git? Github when MS doesn't use github? Or you think MS is going to be able to drum up some business just because they use git? Please elaborate!
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.
