They're doing this because you could easily abuse it. Alot of times you have to make a decision in the moment cuz you hit a luring trap for example. Then you have to decide what you're going to do in a split second. If you'd be able to pull your internet plug and not loose, you could just think about it while not being in there. Make a plan how you solve this etc.. That's why it's allowed in Trust, cuz no one cares about that. You can't get something prestigious in there. Potd clears, especially solo are meant to be super special. And they'll throw everything in your way to make it feel that way.
