Maybe this is a 4D chess move by Mozilla, making everyone leave Firefox which makes Chrome such a monopoly that Google has to split with it. Or maybe it's another braindead CEO or CTO pushing AI into their product because it's the latest fad..
Thank jebus that Vivaldi has said they won't go down that route. They may not be 100% FOSS, but I trust my Norwegian brethren more than whatever Mozilla is doing.
