Looks good, but needs additional specificity / testability.

> No hidden costs

What is a "hidden cost"? Sometimes pricing is complicated. For example, shipping and sales taxes vary based on the customer's location.

> No making it difficult to cancel/unsubscribe from a plan

Maybe: "An authenticated user must be able to review their past and upcoming charges within 2 clicks from the default view. This page must provide immediate options for cancelling/unsubscribing (2 additional clicks to allow for confirmation)."

Or weaker: "Users must be able to cancel/unsubscribe by any mechanism that they can use to sign up / subscribe. For example, if users can purchase a subscription on the website, a they cannot be required to make a phone call to cancel that subscription"

> Automated emails to not self generated mailing lists/social platforms

I don't understand what this means. Are you trying to prevent the companies from using third-party advertising targeting? That seems like an unreasonable ask. It would prevent using Google/Facebook/Twitter for basic marketing tasks.

> No spammy follow up emails

This is not testable. It would be more valuable to identify quantitative best practices and publish those. e.g. "When a user cancels a subscription, do not sent them more than 1 marketing email per month asking them to re-subscribe"

> Allow recipients to easily unsubscribe from mailing-list emails

This should be covered by the "no making it difficult to cancel" clause.
