This has little to do with git vs SVN and everything to do with an inflexible and inexperienced know-it-all being incapable of even trying to pick up an older technology. Read through his replies to the comments, it's sad to see really.

You could have replaced the topics of svn and git with C++ vs python or stored procedures vs parameterized queries and it would have been practically identical apart from people would have told him to sod off and grow up instead of changing their process.

That's actually the only positive take away from this article, it is actually really easy to change version control system if you want to.

I must admit I'd love to see the post he'd make after being forced to use MS VSS :)
