What is FOSS?
FOSS (Free and Open Source Software) is asoftware licensing model that allows anyone theliberty to use, extend and distribute the software
as they see fit. Represents a spectrum of licenses.
FOSS is unique as well in that it producesinnovation quickly by the very concept of open,
cooperative, collaborative sharing anddevelopment.
Commercial software is much more restrictive.

FOSS vs. Commercial
Licensed with very specific rights associated withits use, modification, distribution and use that arenot commonly available to a user via commercialclosed software.
Software licenses of traditional commercialsoftware define specific permission, rights andrestrictions.
Licensee determines the license terms.
Much more restrictive that FOSS. Freedom, sharing, collaboration are not inherit
parts of this traditional closed model whichtypifies the traditional software industry.

Perception & Ambiguity of Free
Free software inherently exists in thecontext of capitalism and free enterprise,not outside it.
Problem was the term free was nothelpful in selling software.
If its free what would you be buying?Ugh!
Who would champion such a cause?

And along came the OSI
OSI non-profit created in 1998by Bruce Perens & Eric Raymondto promote open source.
Open source was a repositioningof free software with a term thatwas to clear up the ambiguity
seen in the term free.
Attempt was to make freesoftware provide a more businessfriendly effort with less of thedeep idealogical slant.
Uphold and promotes OpenSource Definition.
