well you win the Internet Pedantic award today.
So Internet costs $60
TV costs $60
But if I add a phone line I get all 3 for $90. (Or more accurately they give hefty discounts on the Internet and TV with the bundle) So yes I'm getting services for 'free' if you want to be anal about it.
That's 'forcing' you to get the bundle to get the best deal. Yes you have a 'choice' to pay more, but if you want the cheapest deal from a particular provider you are 'forced' to choose from what they offer.
In my case, I'm lucky enough to have both FIOS and Comcast servicing my street so I do have a 'choice' in ISP. Most people, however, don't have that choice and thus are 'forced' to deal with the only 'choice' that they have.
Of course you are also making a huge assumption. That Comcast/FIOS/ISPs are charging the minimum they can for Internet access. In which case the 'bundle' price would indeed be a loss for them. Except that since they are local monopolies in most places, the prices charged for internet and TV are far far far higher than what it actually costs them to provide it.
