It's on the page that describes the new builds, with a rationale:

Unfortunately, it's really out of our control. There is only one version of the runtime we depend on that works on Windows 7, and we would have to use a compatibility library to even use that. That version will lose support soon as well.

It's important that the build system run a supported version of windows, so that it can be fully patched, and have all its security fixes applied. That's safety for every user that downloads chirp. In order to do that, it has to be running a supported windows and a supported runtime.
