Re: "That's an argument that doesn't address the problems with the EME"
"EME is all about DRM. And DRM exists to protect contents from piracy."
Yes, I'm with you so far, as long as you acknowledge that DRM exists for a lot of reasons beyond preventing piracy.
"The only one who have issues with DRM are those who want to pirate contents easily without the hassle and the risks of breaking it."
...and this is where you're wrong. DRM (and the EME) causes plenty of downstream issues, both technical and societal, for people who have no interest in piracy whatsoever.
