This is my own opinion and not the opinion from the team (because we hadn't the time yet to debate) but I would agree with Deve.
Let's not be fanatic, I think mozilla simply had no choice, they have only 25% of the market if people can't watch their netflix on Firefox their market will simply plummet. It might be sad and all that but it's simply true. People don't care that much about freedom in software.
To quote one of the comment
I don't think it's that simple. Just suppose Mozilla had decided to stand up against DRM, once again. What would have happened?
Ultimately, Google, Microsoft, Apple and consorts wouldn't have cared and would have stopped trying to properly work on Firefox, and their sites would only work on Google Chrome, Safari, Internet Explorer... Firefox would be left out.
When Baker says "Mozilla cannot change the industry on DRM at this point.", I think they are right. For years, Firefox usage has slowly but constantly declined since mid-2009 and is now around 25% of the Internet traffic, according to w3schools. Firefox is not the biggest player anymore, Chrome is.
Sure, 25% is still a thing. However, if Youtube or Netflix stopped being compatible with Firefox tomorrow, most people would stop using it. It's not the other way round: too few users care enough about an Open Web to boycott such huge services.
Unfortunately, because Firefox isn't the main actor anymore means that standing up alone against DRM wouldn't have as much power as it would have if they still represented more than 40% of the traffic and were the biggest browser. Had they tried that today, they'd have probably died in the end.
And I think Firefox's survival is more important than a completely DRM-free Internet, which already wasn't DRM-free anyway: think about Flash Player... Even with the rise of HTML5, many popular websites are still using it. And are you really boycotting it?
Well, maybe you are. But still, people with a completely anti-DRM stance are but a small fraction of Internet users nowadays. Because they know that, they can't afford at Mozilla to just deprive the average user from their daily Youtube/Netflix and only keep among their users those rare people that are ready to completely boycott those services.
