Some time ago I wrote a post referring to the GPL / EPL licenses incompatibility. To the letter I wrote at that time and sent to both the Eclipse Foundation adn the FSFEurope, I never got and answer from FSFEurope, but I got several directly form the Executive Director of the Eclipse Foundation, Mike Milinkovich, who was very helpful in getting a good picture of what the problems are.
At the time of sending my email, Eclipse Foundation and FSF were discussing the GPL/EPL issue, so I didn't get a direct answer to the questions in the open letter, but now there is a public answer about the issues available:
Here the point of view of the Eclipse Foundation can be found.
And here the public statement of the FSF.
I will definitely not comment here. Wait for you guys in the mailinglists for a nice chat about that.
