That was Bill Gates. Bill Gates founded the company on BASIC and seemed to remain a fan of the language even as the rest of the world moved on to other languages.
Ballmer wasn't technical so appeared to have no skin in the game of which language "won", so long it was Microsoft Developer Tools like Visual Studio developers used to work on it (and what would become VS Code, which as many point out did start under Ballmer's tenure). That "Developers! Developers! Developers!" meme was directly an "I want to support developers wherever they are and however they want to work". Sure he was a huge Windows cheerleader and would want those Developers working on Windows machines, but he really did seem to want to see Windows be the best platform for developers to code for anything (including/especially the cloud).
In terms of Python specifically, IronPython was active and interesting during Ballmer's tenure and Ballmer helped form a team that was actively contributing to open source projects like Python (and Node and Redis and others) to make them all run better (sometimes much better) on Windows. Ballmer may have been afraid of open source as a business model, but he also seemed to realize the usefulness of open source for bringing developers (back) to Windows and he did start efforts in that direction.
