I applaud your call to action, because it will take decades until these new monetization models can fully take the place of the current ones. The whole infrastructure needs to mature, and the reason why many crypto-related services and businesses use the old models is simple: it is easy (and of course, many of them are just a cash grab). Even Steemit itself, arguably one of the most accessible blockchain applications is pretty cumbersome to use compared to similar non-blockchain platforms.
