Even at scale, running a Relay should be well within the means of a motivated individual or org that is willing to spend hundreds of dollars per month. Right now it'd cost just tens of dollars per month to run a whole network Relay. Some people are already doing this I believe.
Running an "AppView" (an atproto application aggregator/indexer/API server) is generally an order of magnitude more expensive and complicated. But still not beyond the reach of a user coop, non-profit, or small startup.
So these services should all be well within the capabilities of at least multiple companies operating in the atproto ecosystem as it scales.
And in many cases it should make good sense for these companies to do this since it will improve their performance by colocating their services and enable them to do things like schedule their own maintenance windows, etc.
