The way I see it (I'm thinking along the lines of deplatforming more than outages)...

Theoretically the AppViews are replaceable (assuming they're open source)

If the relay blocks your PDS and you connect to another relay, you need the entire rest of the architecture to also connect to that other relay to maintain your apps and frens

Each relay ingests the entire network

Each component ingests the entire network from each relay

So that's double the resources per component for 99.9999999% of the same data

Who is going to pay for that 🤔

I think it would have to be the new relay provider

Then where is the demand coming from to cover those costs
