I wonder what are the odds of Visa being succesfully sued for processing payments to such a huge brand like Steam. Steam has its virtual wallet and marketplace as well, so Visa is twice removed from where the money will actually go once it enters Steam ecosystem. Even as an abundance of caution, this doesn’t make sense to me.
