Open Source Software (OSS)

OSS literally means software whose source is open. Stretching this
definition, to be termed OSS, the software should also not restrict
the user from freely using it, modifying it and distributing it. The
most significant differences between OSS and Proprietary Software
(PS) are immediately apparent. PS is usually distributed as a binary
without the source code. So it is almost impossible to dissect the
program to learn about its structure and logic, and make correc-
tions or modifications if necessary. PSS is normally sold with a lot
of conditions that restrict the usage and distribution of the program.

There is a general opinion that all OSS is also free of cost. That isn’t
the case. Proponents of OSS do not restrict the sale of the OSS.
People are free to package and sell OSS at a price they consider fit.

But given the fact that the OSS is freely available to the next person
as well, it is easy to conclude that it would not be possible for an
arbitrarily high price to sustain. If the price is too high, other ven-
dors will enter the market and sell the same product cheaper. Thus,
market forces will ensure that only a fair price is charged.
