> It's a small minority

Is it really a small minority? I have never worked on a project that didn't have commit messages that at least tried to be descriptive (sometimes people fail at it but its very different to an outright "changed stuff").

I don't remember any friend mentioning to me them encountering a work project where the messages were totally neglected either.

Never seen that in any company I worked at either and I can’t believe professional developers seem to think that it would be ok to write meaningless commit messages. That’s just so sloppy.
