I like that phrase. It sums up what Linux is to the home user. Some scientific users look at it that way too, sometimes out of budgetary necessity, and sometimes out of pure interest.
There was a similar topic to this some years ago
One quote from it
" In Windows paying customers are treated like children who can’t be trusted. In Linux, users who pay nothing, are treated like paying customers."
Dont agree. I think Linux users are treated more like shareholders than customers.
