The change shouldn't just be towards more clarity, it should be towards permissiveness.
It's unacceptable that a few companies have so much power on economic transactions and what can be sold online.
If I may ask, why?
Wouldn't introducing the option of paying through cryptocurrencies at least partially address this issue?
(Disclaimer: I own nothing in cryptocurrencies, I am not attempting to promote anything, it just seems like an obvious patch for this issue).
