We went through this already. You could be “forced” in the same way before. And by “forced” you mean “have ramifications for not abiding by rules I agreed to.” If you agreed to no rules and they drop the sudden requirement on you, I fail to see how you lose out in any way shape or form. You get the loot, and you don’t have to put up with toxic morons again.
A group in PL that actually cares about funneling loot from people is either going to make exception for pugs they bring in, or count the drops to see if anyone is attempting the modern day equivalent of a ninja looting and act accordingly.
Great, in the vast majority of cases in both PL and GL, that’s how it works. Enjoy GL, it’s made just for you!
