Mozilla had no choice but to add DRM to Firefox

But did the folks at Mozilla really have a choice when it comes adding DRM? An open source project like Mozilla is not immune to market pressures. And with so many competing browsers such as Chrome adding DRM for Netflix, etc. how could Firefox avoid adding it? Is it realistic to think that Firefox can simply ignore such things? I don’t think so and the reason why is in Firefox’s usage numbers over the last few years.
