Your criticisms are valid, though I think they are a tad bit paranoid. Do bitcoin miners influence Dev? Yes. Can they introduce changes 51% of the network disagrees with? NO.

Does #[6]​ have more influence than me on nostr devs? Absolutely yes. Will he be able to introduce an algorithm into nostr protocols without EVERYBODY being able to see it and being able to disagree with it in an actionable way? NO. This is not the bird app.
