Subversion is simple to understand because it is simple, and relatively incapable. If you only use git like you would use Subversion, it's simple too. Subversion is much less easy when you have to do something like merging a long-lived branch.
You conveniently omit the inclusion of mercurial in the list. Mercurial is as powerful as git is--in a few cases, arguably more so (phases make history rewriting safe!)--and yet there is pretty objectively far less confusion for newbies than git has.
There's ample evidence that git is unnecessarily complicated for the DVCS model it uses.
