Can anybody explain what is the difference between GPL v2 and GPL v3.
And why is versionn 3 considered not good by some people,
also same for version 2.
How was GPL v2 used that it has raised the need for new version?
Bare in maind that I could read both licences but probably would not
understand what is there talking about. Actually I read GPL v2
and as I understand it is:
if you use code under GPL your program has too be under GPL.
Is this not correct (somebody suggested that come companies find legal
way to use GPL code for proprietary program - how to)?
