They not only offer hosting costs and coins in wallets ... they also offer services that this network of nodes manages and that enrich the project.
I would argue they impoverish the project in the current protocol configuration.
These "services" cost nothing to provide over and above hosting cost. Yet the blockchain is charged $32M a year for them.
If a treasury contractor wrote a service-provision proposal who's budget accounted for 99% profit margin they'd be likely to get thrown out the door. Saying that the 1% worth of service provision "benefitted the network" would be unlikely to help them.
