I wonder if the term "DIY Software" would better describe the Free Software movement?
It's lacking in the lofty idealism - but maybe that's not a bad thing?
"DIY" captures the freedom-to-use and freedom-to-tinker elements well... It also sets expectations about the relative lack of polish compared with consumer products.
Maybe we're too serious for our own good.
