You’ve got some good points here! These standards are usually enforced by law, just Valve/Steam is extremly liberal on his marketplace. But I fully agree, then the other bodies do not need to interfere, especially when they are so hard to be checked.

Edit: Still, in some way, I wish that companies throughout every service chain would implement and follow these moral standards and laws. And follow though, if they find negligence by other parties. (Kind of a “check and balance” thing.)
