Established players aren't selling on all platforms. Any platform doing more than $1bn in ad revenue operated their own ad sales platform.

The only players that sell through third parties are sub-scale publishers, and that is a shit business to be in. If that's what OpenAI is aiming for then they will never be able to compete with Google.

I'm not really sure what you're analogy about Coke is meant to mean here...
