The devil is in the details

Parent article: IBM's patent pledge
So, a high profile company with patents of their own decide to take IBM up on the offer - and include some IBM patented technology in an open source project. (Perhaps the engineer doing so thinks; "hey, IBM licensed this for open source projects - I don't have to ask the legal dpmnt for this tiny detail.")
By doing so, the company has effectively licensed _all_ of their patent portfolio to open source projects. IOW IBM withholds all but 500 patents, but in doing so they deny anyone who take them up on their offer the ability to withhold anything at all.
This is a very unbalanced license.
