The insidious nature of ad-supported “free” media where end user is the product delivered to advertisers means that even if you reverse engineer some service and develop a third-party client that totally respects ads and all and simply reduces the addictiveness, tweaks the algo, etc., you are still reducing their revenue because people will see fewer ads if they spend less time on the service and probably have more fulfilling lives.

This business model is poison. Service operator’s interests will never be aligned with the interests of the users unless they are paying customers.

(By contrast, if the users were paying customers, Google would have no problem with your client—it would in fact be saving money on compute & traffic.)
