Jimmy John's used to make the teens that made your sandwiches sign non-competes. It stopped after this became public causing horrible publicity and lawsuits from the New York and Illinois attorney generals.
FTC is probably overdoing this though; I sat out a full year on a compensated noncompete couple years back for a very good reason and the use case is still very much there for industries with sensitive information.
Proscribing noncompetes will make hiring very difficult going forward - one bad hire and your alpha walks out of the door...
