Despite our dislike of DRM, we have come to believe Firefox needs to provide a mechanism for people to watch DRM-controlled content. We will do so in a way that protects the interests of individual users as much as possible, given what the rest of the industry has already put into place. We have selected Adobe to provide the key functionality. Adobe has been doing this in Flash for some time, and Adobe has been building the necessary relationships with the content owners. We believe that Adobe is uniquely able to bring new value to the setting.
Talk about being between a rock and a hard place. Don't include DRM, and see your userbase erode further. Do include DRM, and you go against your organisation's core values. If you go for the former, and your userbase erodes, you run the risk of not being able to express your core values at all.
