I can't tell if this is satire. Does anyone seriously believe that surrendering the war when you've lost one battle is an intelligent strategy? Mozilla contributes a whole lot to OSS, including providing a browser that can be trivially used without any black-box DRM-enforcement code hitting your system.
I didn't mean to suggest I categorically disagreed with the decision, in this case. I simply note that you can't extend that logic indefinitely, or you lose the thing you're fighting for.
