At least wikipedia has an out in the legislation by disabling content recommendation engines for UK users, this includes:

1. “You may be interested in…” search suggestions on the Wikipedia interface—these are algorithmic, content-based recommendations.

2. Editor suggestion tools that propose pages to edit, based on prior activity. Academic systems helping newcomers with article recommendations also qualify.

Most links within articles—like “See also” sections or hyperlinks—are static and curated by editors, not algorithmically chosen per user. That means they do not meet the recommender system definition.

The legislation text for reference:

"Category 1 threshold conditions 3.—(1) The Category 1 threshold conditions(10) are met by a regulated user-to-user service where, in respect of the user-to-user part of that service, it—

(a)(i)has an average number of monthly active United Kingdom users that exceeds 34 million, and

(ii)uses a content recommender system, or

(b)(i)has an average number of monthly active United Kingdom users that exceeds 7 million,

(ii)uses a content recommender system, and

(iii)provides a functionality for users to forward or share regulated user-generated content(11) on the service with other users of that service.

(2) In paragraph (1), a “content recommender system” means a system, used by the provider of a regulated user-to-user service in respect of the user-to-user part of that service, that uses algorithms which by means of machine learning or other techniques determines, or otherwise affects, the way in which regulated user-generated content of a user, whether alone or with other content, may be encountered by other users of the service.
