I don't understand why so many opinion pieces and news keep on saying that Web Environment Integrity could be abused and that's why we should oppose it. This misses the point a great deal.
Implementation of Web Environment Integrity in browsers IS ITSELF AN ABUSE, because
I have the right to go around the web without continually proving who I am, even less against a 3rd party.
It's as if someone said that some officer (and not even a government one) should always be by your side when you go out, ready to certify who you are, whenever you speak with people on the street – and even with friends. Would you accept that?
Will have to wait and see how Apple reacts with Safari. Mozilla dismissing the proposal is big, but Apple has the second largest mobile OS marketshare with iOS, and so Safari is very relevant for websites to support it.
I can't honestly see how any other company can single-handedly stop Google if they go though with this. Google has the ability to strong arm this proposal by having Youtube and Google search dependent on Web Environment Integrity. There are enough alternative to web search but I can't see how anyone can fight Google's dominance in video hosting to stop them.
You would almost have to have every other major website intentionally break on Chrome to even the playing field, and if Google still don't back down you are left with a divided internet.
At this point, why don't the companies who run Chrome derivatives work together to build a fork that evolves separately from Chrome? Edge, Vivaldi, Opera, etc. will never get the marketshare on their own to rival Chrome, but together, they could make a dent with a unified browser engine.
Looking on the bright side here, this will be good for applications that depend heavily on Chromium such as Steam. It won’t be much good, but it’s something.
Brave and Vivaldi (and edge) have no say in the matter, they are practically in the business of rebranding chrome for what it is and contributed to reinforcing goggle's monopoly. I have absolutely no sympathy for them.
