Um actually… Opera and Edge weren’t always based on chromium!
Chrome was not always based on chromeium. Chrome was based on Apple WebKit until 2013 when they forked WebKit and made the Blink engine.
Pre-Chromium Edge wasn’t even that bad. Sure, the engine had its issues and there was probably a bit of Edge-specific JS on some websites, but I’m sure they would’ve eventually got there.
But seeing that even Microsoft abandoned making their own browser engine, it goes to show how complex it is to make one nowadays and with new web APIs/features coming out every few weeks it feels like, it’s almost impossible to keep up.
Brave, Vivaldi, Edge and other chromium browsers are forks of the main chromium project. They can decide whether to include or exclude features from mainstream chromium.
As far as I know, Brave and Vivaldi will keep Manifest V2 extension support and said that they will not ship WEI (Web Environment Integrity).
Discord uses a modified version of electron, and it’s also probably an outdated fork as well, although I am not sure about that.
Steam, in the other hand, uses CEF, which they use as a way to render it’s interface and as a replacement of VGUI (a good example of this is the steam game overlay), I don’t know if they will ship WEI if it ever releases in chromium as there isn’t a statement from Valve yet.

This is why I’ve stuck with firefox through thick and thin
Firefox died long ago.
It was an engine fight, and Mozilla decided not to participate.
