I would say the FCC had a talk with them.
Does the FCC have jurisdiction over car manufacturers?
The FCC did mandate, many decades ago, that TV manufacturers provide TV sets with equivalent VHF and UHF dials.
The early sets had clicky VHF dials, but smooth turning UHF dials (like radios). UHF stations complained that TV viewers preferred clicky dials, so smooth dials put UHF stations at a disadvantage.
When I was very young, my parents had an old black & white TV set with smooth turning UHF dials.
