Recently I read often that #copyleft is so bad, that nobody want to use it. I think this depends on the definition of use. People who are looking for some free beer to build their own proprietary stuff might feel sad because they can't (ab)use copyleft software. End users couldn't care less. People who want to get engaged typically like copyleft because it creates a level playing field, nobody have to fear that a competitor will take their investment and run away. #FreeSoftware #OpenSource
