It's just `latest` tags, it will also affect any other image tag.
If you've been referencing org/image:tag where tag=major-minor, and gets updated when there's a patch, then that's going to stop getting updated.
Without either the tag being deleted (and thus your pulls failing), or going out to find updates on that container - you may not notice that it's fallen out of date and the image/tag is no longer being updated.
With the entire organisation being removed from Dockerhub, it sounds like there's not even going to be a way for people to say "We've moved off Dockerhub, our images/source/etc is now over here".
You'll just have to search and hope you can find where it's moved to.
