This is really a big misunderstanding. If rate limiting was the problem and if that node was creating issues. We have a bunch of other nodes for Hive Engine that can be used. You can have your own node too for your tasks. The data is going to be anyways on-chain. If you have challenges in creating and maintaining a node, I also offer that as a service. You can contact me.
It is also not a hard task to create an intermediate app that will rotate nodes based on availability. I have done that for my apps as well. Also, this is a blockchain feature and not something specific to Hive Engine alone. @rollie1212.
Hive will also have a similar concept. That's why people rotate their nodes and use them. If it is blockchain, this concept is very common.
