"In one sense, the idea that all we need is a mostly free
operating system is a direct indication of where FOSS is today.
Most types of software needed for productivity and leisure
computing are now available as FOSS applications, and those that
aren't, such as Flash, or video or wireless drivers, are available
as free downloads with proprietary licenses. This state of affairs
means that, if you don't care about licenses, for the last few
years you have been able to run most GNU/Linux distributions
without any inconvenience."
