Your boss doesn't micro manage

You should be taking care of this, not Billy

Firing a team member for a team mistake is micromanagement.

I’m assuming Billy was fired because Sally made an unethical or illegal change.

Billy did nothing wrong!

What's the other options besides hg if it ain't git?

SQLite uses Fossil.

Bazaar used to be an option: http://bazaar.canonical.com/en/

Pijul is very promising: https://pijul.org/ and https://pijul.org/manual/why_pijul.html

Merging A in B should yield the same result as the opposite with Pijul, etc.

darcs is still actively developed and it has a niche in the Haskell community.

Ubuntu might still use Bazaar.

BitKeeper is one, Fossil is another. Then there are non-DVCS systems like Subversion, Perforce, VSTS etc.

SVN still works well for our company.

Thank you, now i am resting assured.
