I guess the current situation could be better if Opera and Brave coordinated among themselves a shared codebase for a patch that would allow both of them to keep v2 working. The thing is that Brave most likely doesn't actually care, they've a built in adblocker so if v2 goes away then their marketshare will increase. Opera can't do it alone because, well it is the Opera Chinese owned company after all.

I was really hopping that Microsoft would take on this, think about it, from a strategic PoV if Edge kept v2 and advertised it they could just snatch a big chunk of users from Google.
