Verizon is, last I heard, the only one trying to break the grip of these automatic inclusions. E.g. see Choice packages. others may try and follow their lead.
On the other hand most of them are now charging extra fees for Regional Sports and Local programming. They are losing ground to non traditional TV services.
Cable is regulated where there is no competition. But a number of places have competition ( they only need 50.1% overlap) to not be regulated. Just like electricity and gas. My service is regulated, but because other providers can sell to me, they can charge whatever they want.
The reason for some of the fees ( regional sports and broadcast) are to push the charges where they are levied vs making everyone pay. If you are in an area with lots of sports networks or ones that charge more, you pay more
