For the first problem, I would argue the tools people work with and the formats they publish should be two completely different decisions. Work however you want, but sure as hell publish in a standardised format supported across the organisation.

For the second problem, I guess I don't have much to say because I haven't tried running a large company. I just have never heard any good reason to be stingy with licences. On the other hand, the time I have wasted and the extra work I have done to get around problems caused by upper managment being stingy with licences has cost a lot more than the licence would.

I guess this will immediately make people discard my opinion, but I don't actually feel very strongly about each team having its own formatting rules or coding standard. It's not hard to adapt to the local conventions and the consequences of formatting rules are incredibly local.
