True, I have forgot that "I use this SCM" (or "I used this SCM") doesn't
necessarily mean that one _choose_ this SCM.  One can use some SCM
because it is SCM project uses, or because their company requires it;
but not necessary, as git-svn and git-p4 show one can use Git, and
make it interact with respectively Subversion and Perforce, and trying
to make it look like one uses this other SCM.

I hope not.  Even Microsoft themselves supposedly doesn't recommend
Source(Un)Safe, but MS Visual Studio Team System.

Right.

I don't think 59% (in the example case of using currently Subversion)
is small.  Take into account for example that there are people who (as
seen from responses to other questions in this survey) use SCM (Git)
only to track their private work, never publishing.  Then there are
people who do not track (perhaps with exception of web interfaces)
other projects development using version control systems, even if they
do follow their development.

Side note: the number of replies in "still use" category agrees with
other data, like mentioned Ohloh stacks, or Debian popcon (package
popularity), or Newren research, or vcscomparison research.
