But the reasoning that is advanced is rarely as forthright. It is always couched in devious language but the arguments are generally as mendacious as they ever were.
The latest "why we don't need the GPL" argument comes from one Donnie Berkholz of an analyst firm called RedMonk. It begins with a falsehood: "In the early days of the GPL and copyleft software, it played an important role in forcibly training companies how free/open-source development worked." No, it did not. The GPL, being a free software licence, had nothing to do with open source at all; it was about ensuring freedom for users, freedom of the political kind.
The man who wrote the licence, Richard Matthew Stallman, was keenly aware of the one human factor that nobody could control - greed. Hence he put in the requirement of share and share alike to ensure that nobody could profit from another's efforts without contributing back something themselves.
The concept of open source was born in the late '90s, an initiative by Bruce Perens and Eric Raymond to make what was called free software acceptable to businesses. It is a development method. It has nothing to do with ideology or freedom. There are numerous open source licences that do not even qualify as free software licences.
