App dev can be outsource, but it really doesn’t matter who run the hard coded instance. It could by. Sh.itjust.works. it would be an issue if the app took off and the instance wasn’t ready for the influx.
Maybe it picks an instance at random to distribute the load.
My original idea in my head was that the app developer would run the instance that was hard coded



I’ll make a post on c/ fediverse and open source to generate ideas of how to do this this
