F.L.O.S.S. vs. Proprietary Software

How to make the difference : Examine the licensing terms:

  • In theory, it's quite easy : see the table bellow.

  • In practice, consult the experts.

Basic picture :

Table 1. Rights granted

  Proprietary software FLOSS
Right to use : Yes (but limited) Yes
Right to study : No Yes
Right to modify : No Yes
Right to copy : No Yes

Sometimes, vendors tend to invent complicated licenses, and it becomes hard to interpret the licensing terms.

So rather trust experts : Free Software Foundation (http://www.fsf.org/), OpenSource initiative (http://www.opensource.org/).
