That is some serious wishful thinking.
Maybe... But DRM is the case for now with or without Mozilla. There is no way the content industry will let NetFlix and Hulu will drop DRM right now.
So what is the alternative, denying people NetFlix and Hulu? We all know they'll go to Chrome and IE, or NetFlix will make a binary plugin for Firefox, which won't be sandboxed.
The only reason DRM went away on music is because Apple did some economic jujitsu on the publishers making them choose between money or control, apple's complete domination of music DRM meant they could dictate terms to the industry as long as the industry required DRM.
Let's hope netflix grows powerful enough...
(1) Why do you think they encrypt the streams individually instead of just once and store the encrypted files on their server just like bluray discs of the same movie all have identical encryption?
NetFlix don't implement DRM out the evil in their hearts :)
They do it because the content industry requires it... And the content industry requires each stream to be encrypted individually... They require a complicated protocol that ensures that each device is uniquely identified...
Security through obscurity is complicated (no surprise there).
(2) Encryption is super cheap now that dedicated hardware is built into modern CPUs - a typical Xeon processor can do 700MB/s with AES-NI on just one core. Intel makes Xeons with 15 cores per chip nowadays.
But building a large CDN with this kind of special hardware is expensive, very expensive. Without DRM movies could be streamed directly from a normal CDN.
