I'm glad that the article writer got his domain back, but I wish we had a better term than "grandfathered". The origin of this term goes back to Jim Crow, when to stop Black people and newcomers from voting, many places in the American South imposed a near-impossible test you had to pass to register to vote, but also added a loophole: if your grandfather voted in your county (or sometimes your state), you could vote without taking the test. This was called the grandfather clause.
