> Any choice of what content to display is an algorithm. Maybe they want a simple or easily explainable algorithm?

That's a paraphrasing of what law says. The law is more clearly defined:

> "Addictive feed" means a website, online service, online application, or mobile application, or a portion thereof, in which multiple pieces of media generated or shared by users of a website, online service, online application, or mobile application, either concurrently or sequentially, are recommended, selected, or prioritized for display to a user based, in whole or in part, on information associated with the user or the user's device, unless any of the following conditions are met: (1) the recommendation, prioritization, or selection is based on information that is not persistently associated with the user's device and does not concern the user's previous interactions with media generated or shared by other users; (2) the recommendation, prioritization, or selection is based on data controlled by user-selected privacy or accessibility settings or technical information concerning the user's device; (3) the user expressly and unambiguously requested the specific media, media by the author, creator, or poster of media the user has subscribed to, or media shared by users to a page or group the user has subscribed to, provided that the media is not recommended, selected, or prioritized for display based, in whole or in part, on other information that is not permissible under this definition; (4) the user expressly and unambiguously requested the specific media by a specific author, creator, or poster of media the user has subscribed to, or media shared by users to a page or group the user has subscribed to as described by paragraph (3), be blocked, prioritized, or deprioritized for display, provided that the media is not recommended, selected, or prioritized based, in whole or in part, on other information associated with the user or the user's device that is not permissible under this definition; (5) the media is direct and private communication between users; (6) the media is recommended, selected, or prioritized only in response to a specific search inquiry by the user; (7) the media that is recommended, selected, or prioritized for display is exclusively next in a preexisting sequence from the same author, creator, poster, or source; or (8) the recommendation, prioritization, or selection is necessary to comply with the provisions of this Act. "Addictive social media platform" means a covered platform that offers users or provides users with an addictive feed as a part of the service provided by that website, online service, online application, or mobile application.
