I'm not sure that a change to the actual text needs to be made. It's pretty general as it is, and says several times not to expect support for third-party uses. It may be helpful to add a note at the top (or at the top of the "Using maps in third-party services" section) saying that third-party access is no longer generally available. Leaving the rest of the information about third-party services is important for the allow-listed sites and in case the Foundation decides to allow broader third-party access in the future.

In any case, the TOUs are Legal's responsibility. I've dropped legal@ a note as well.

As the WMF-Legal project tag was added to this task, some general information to avoid wrong expectations:
Please note that public tasks in Wikimedia Phabricator are in general not a place where to expect feedback from the Legal Team of the Wikimedia Foundation due to the scope of the team and/or nature of legal topics. See the project tag description.
Please see https://meta.wikimedia.org/wiki/Legal for when and how to contact the Legal Team. Thanks!

Thanks, Maps folks were already on it.

We announced an upcoming change to the Maps Terms of Use, going into effect on April 5, 2021, to address the point raised in this ticket.
