They should pay the hosting costs of any server they pull data from
not run ads against the content that comes from other instances
Any changes they want in activity pub should be in the form of an MR on activitypub itself, and they must respect the protocol maintainers of the project if their MR is rejected. If they implement AP features outside of spec, they should be summarily defederated. We do not need another Jabber/XMPP vs Google situation
Any instance is free to federate/defederate with threads
