Are the companies that offer honest service disadvantaged in the long-run? Sure, in the short-term, a captive audience is profitable, but eventually, this should harm LTV?
I don't see how they would be advantaged. Their users are leaving, the chances of re-subscribing are small, while the users of their competitors are not leaving. Their honest service is a small thing to matter in the overall perception of their product, especially when the biggest names in the sector are using dark patterns.
