In my thinking, I probably should have said cooperative instead of marketplace -- a place where all parties have equal access and there's no tax to a third party.

App stores, ad markets (as they exist today, namely Google/Facebook/Amazon), and Facebook user feeds are all beholden-to and -enrich a single operating party. And specifically, an operating party that also competes with many of the offerings in their own "marketplaces". That makes them owned platforms in my book.

That sets up some screwy incentives (e.g. caring about volume over quality, self-preferencing) that substantially degrade the entire experience for buyers/users.

To the email case though, the problem with penalties is that they require a centralized manager. Which is how you get back to Gmail being a de facto standards body. Ugh.

We could always have done net-zero charging on email fees, that I think would have solved the accessibility issues. $0.05 paid to send an email -- $0.05 earned on receipt of an email.
