Dana Blankenhorn from ZDNet writes on the hard truth of FOSS development-

Mr. Buzzword for February appears to be proprietary open source. This is an open source project which is owned or controlled by one company. Even though it may have a GPL license, you have no more power over it than a single voter in a political system.

The definition has changed since I first wrote the Open Source Incline back in 2006. It’s now a development model, not a licensing model... You have even less control over the project’s business model. If the “owner” wants to let someone do a proprietary fork which undermines your work, there may be little you can do. Especially if you happen to work for said owner.

And Big Blue ...must eat, as a commenter e-mailed me after I praised IBM’s Jazz contributions. They (IBM) do want to lock people into buying Rational tools, he said, and open source is a means to that end.

Now thats applying standard economics to FOSS: FOSS developers are not revolutionary warriors taking on corporations, elements of control still affect development in free information and IBM needs to make a paycheck.
