This is a bigger PR disaster than Xbox One. Everyone is criticizing Opera for the gutted features.
These are the old users who are whining. Opera's old user base is a good riddance. Opera was a slow, bloated browser, which no-one wanted to use. Now it has a chance at being a decent browser and acquiring a new user base, who doesn't care about those 'gutted features'.
Now it's bigger with less features.
The market share of power users might be smaller, but there Opera at least had a chance. Competing for the "I can't do shit so I don't want options" crowd against Google and their shamelessly emotional ads? No chance. No good reason to even try, either.
