The point is to gather data on how this behaves in the wild. If the study is opt-in, then you have to try to figure out what part of the effect you're seeing (if any) is just selection effects.
Controlling for selection effects is possible if you have enough information about who is selecting into the study vs not selecting into it to see whether there are biases in the study participants. But doing that requires having _way_ more information about the study participants than Mozilla has or wants to have.
So this doesn't _need_ to be opt-out, as long as you're willing to not believe any data it produces. But then what's the point?
