Been there, done that. Spoiler alert, it ends with even more people switching to chromium, Mozilla crying that it’s deeply concerned with and extremely opposing WEI and will work on figuring out a better solution, because WEI is not what Open Web should be, but is being forced to implement it, because people are switching to other browsers because their shit ain’t working.
With most competing browsers and the content industry embracing the W3C EME WEI specification, Mozilla has little choice but to implement EME WEI as well so our users can continue to access all content they want to enjoy.
