I seriously doubt any amount of user backlash will help put the genie back in the bottle, once it's out. And nobody is going to change to the browser that can't access the popular site du jour that now requires WEI attestation to access. If WEI gets rolling it'll be impossible to fight.

That said I totally understand this is almost certainly already lost. Chromium's market share is unassailable and there's no way we can convince enough people to swap off it until there's nothing to swap to. It just sucks to think nothing can be done, so please forgive people like me for trying anyway.
