@JulieM Re: Of course, being centrally controlled
They can release compiled binaries (and nothing else) under the Apache licence, or a BSD or MIT licence, and still call it Open Source. "Just exercising their freedom not to share" meets the letter of the law, just not the spirit.
Actually they can't.
They have to distribute the source code.
There are other fallacies with respect to Open Source, but that's not one of them.
I agree that within Open Source there are various licenses and you will find that there are flaws with them.
One could write an economics PhD thesis on the fallacies of Open Source and its impact on the IT world.
That's not to say that there aren't advantages to it, just that its not the panacea that everyone thought it was.
