What is Brave going to do when the code for WEI becomes load bearing in the chromium code base? Still excuse after excuse after excuse to just not use Firefox. I literally don't care if you have to hold up your nose, there's only one actual alternative browser engine, and it's a matter of survival for anyone who doesn't want the whole internet controlled by google. It could be half as fast (it isn't) and use twice as…
Apple because of Safari (duh) and Microsoft because they are possibly the only company that could reasonably maintain a hard Chromium fork in the case of Google going crazy.
Unfortunately all three of them are more or less aligned on this issue of remote attestation so I don't really see a path forward.
Firefox just doesn't have the market share to matter. If everyone had switched to it 10 years ago there might have been a chance but the goose is cooked.
