I thought about that when it happens.. absolutely true, it definitely could be an actor that settled it in order to than introduce the solution whom he'll benefit for.
Thing is, replyguy could have been created and would be by anyone, and a solution would need to be found. Was the one they used the right one, I don't know, and not capable to create a better one, I can just decide to trust who built it and use it, or not.
Optionability is what we have on #nostr.. you like it, you use it, otherwise you fork it or change it, or stop using it. It's all up to us and how much we want to engage and make a change.
