As GP mentioned it has been in effect for a while in Holland and maybe Korea or a few other places for at least certain kinds of apps due to local laws.
Interesting note: this only applies to the US. I know the EU is forcing changes as well, but those are EU only.
So South America, Asia, Australia, Africa, Canada, Mexico, and others haven’t changed one bit and likely still require 30%.
