Another point worth considering is consumer surplus: in the $10 subscription model, Alice actualizes $5 in benefits over what she paid. Merely counting subscription revenue doesn’t capture the surplus to the cookie-eater ecosystem.
So even if the EA service makes somewhat less revenue than the vendor would make on a non-EA gig, it could in some cases still be superior because the EA ecosystem captures the consumer surplus in the former case.
