Another option: It's genuinely easier, for what amounts to namespacing reasons. Like, if I came up with a cool new C compiler, I'd probably name it ${MYNAME}cc just because that's an easy identifier that is very unlikely to have a collision and doesn't require me to spend time thinking of some name that is clever, unique, and accurately conveys what the project is about.
