This is not a refutation, because what you describe is not about the thought experiment. In the thought experiment, there are no Upsilons, and so nothing to worry about. It is if you face this scenario in real life, where you can't be given guarantees about the absence of Upsilons, that your reasoning becomes valid. But it doesn't refute the reasoning about the thought experiment where it's postulated that there are no Upsilons.

(Original thread, my discussion.)

Thanks for dropping the links here. FWIW, I agree with your objection. But at the very least, the people claiming they're "one-boxers" should also make the distinction you make.

Also, user Nisan tried to argue that various Upsilons and other fauna must balance themselves out if we use the universal prior. We eventually took this argument to email, but failed to move each other's positions.

Just didn't want you confusing people or misrepresenting my opinion, so made everything clear. :-)
