Nostr is the most bizarre software market ever, as the tech stack is so thin and thoroughly open-source, that the results are largely the same, regardless of production price. There's the base production price (which is incredibly low) and then there's 99% marketing budget on top.
I.e. the money spent is mostly being used as a signal to inform the users which of the nearly-identical products they should use. Obviously, a widget that costed $100k to build is inherently better than essentially the same widget, that costed $1k to build. Not because they are different, but because they are the same, you need to choose one, but they differ in only one aspect (money spent per feature), so that aspect has to guide your decision.
