I think you are just speculating. If you had a relay, you would know that behavior would just drive people away and your relay would not be used that much anymore. It's better to offer options to pay for longer storage if it gets to that point.

The proof is that every event in Nostr is still fully recoverable, even the ones from 2 years ago. Even large ones.

On top of that, people that want to put up a website are more than happy to pay for the storage. All they want is to not be held hostage by the provider. And Nostr gives them that. They can pay for 5-10 relays in different countries for a cheaper amount than they would pay for CDNs today.

Either way, we will see what will happen.
