I've worked with 20yrs+ senior Devs whose commit message is always something like 1 or 2 words sentence (think of "cleanup", "feature X done") and some of there work manually with diff-tools between their local copy of code and the for repository they check out on a different folder. If they're not satisfied with the incoming changes, they just overwrite them and push the overwrite back to repository.

This has happened with SVN and also is happening with Git.

Unfortunately you can't argue with those ones since are in lead position and there's no one with technical skills above them in the C-level who can say anything (we don't have a CTO or a CIO, just CFO and CEO who can't even use their own iPad)
