I myself introduced SVN as versioning solution to a company in 2007, years after git was available I and I was aware of it
git simply didn't have the mind share jet, thus I went with what I knew
In 2013, I was tasked with writing wrapper scripts around SVN to make it look like SCCS to avoid confusing the development people who only knew how to use SCCS whilst the company migrated to SVN. Fun but traumatising.
Git was too weird for a team, but svn with its linear timeline was a hit. They are still with svn, and for a small shop it's ok
