No, they issue licenses to broadcast on certain frequencies. And some of these licenses dictate what content can be shown and at white time of day (usually to the effect of restricting mature content to evening and nighttime airing). This is because of the nature of how bandwidth is publicly owned, and so the the public gets to decide how to allocate a limited resource. Fines exist to accommodate the fact that certain content can't be censored reliably (e.g. live interviews or shows where someone can go off script), while still creating a disincentive to violate the terms of the license. Any of these publishers could sell tapes or dvds of these shows and face no fines whatsoever. Similarly, they could air them on the internet or on cable television that is not subject to public control of content. There's no restrictions on the content itself, there's restriction on the use of publicly owned bandwidth.
