Ars does not really control that one. It is part of an ad... Why they still run Callisto Protocol is a mystery. But you don't see it if you login with a subscription.
I have never seen this mystery video. I... I have never seen Ars without a sub... Or rather. It has been decades since I have. What Ars looks like without a sub is lost to the depths of time. I am, quite honestly, a little afraid to even check out Ars without logging in. Not even for curiosity. 'cause you know, what happens to cats, you know.
/Edit: oh. Guess you don't have to sub to avoid it, just login.
