I think there's a rather strong correlation between people that are used to the command line and people who don't pay for stuff online because they use opensource products. It doesn't make things better that tarsnap works only on linux of course. (If I remember correctly?)

That might be part of the problem as Davidw is hinting at.

Linux, BSD, Solaris, OS X, and Cygwin. Probably other UNIXy OSes too, but I don't know anyone using AIX or Tru64.

Tarsnap doesn't support Windows (except via a POSIX layer like Cygwin) or GNU Hurd.
