Actually a lot of channels charge the cable company to carry them, ESPN for example. (not all do though)
I definitely understand the business model and the risks to it if nobody watches the ads. That is an argument that the business model may no longer be viable in the coming years however, not an argument for any personal obligation to watch commercials if I want to watch a TV show.
I don't buy that.
First, on cable company payments to the channels: common sense speculation is that that does not replace the ad revenue. They still have the ads for a reason.
It's kind of like saying 'the city gave the movie theatre tax breaks to get them to open it, so it's ok for me to sneak in and not buy a ticket'.
No, it's not ok. The analogy is imperfect on the difference you are legally required to buy the ticket but the point is the same, it's an irrelevant distinction to the issue.
Second, saying 'the business model may no longer be viable' is a euphamism. It's correct, but hides the rest of the issue.
It's like pirating a game whose publisher goes out of business and saying 'I didn't do anything wrong. Their business model was not viable because piracy is easy.'
It's like organizing a flash mob to run into a store and shoplift and run out fast and then saying 'oh, tha put them out of business? The business model didn't deal with it.'
Yes, again, that's technically true - if a business model can't deal with behaviors that make it unprofitable, then that business is not going to be there.
That does not negate the point that the people choosing a behavior are making a choice that can be unfair, morally indefensible, and threaten a business.
Those analogies are also imperfect in dealing with criminal behavior. Let's pick one that's not, because while it's not the issue, why not get rid of it.
Let's say your local car cruising group has a couple hundred cars, and you decide your idea of fun is to go to a local fast food place that only has a drive through open, and for hours you all get in line, get to the microphone, and say you decided not to get anything, ha ha. That this prevent any legitimate sales. Assume this is legal.
Now, that's somewhat similar, in everything except the motive being 'preferring to avoid commercials' versus 'finding it amusing to do'. Not an important difference.
It's a behavior people CAN choose - but one which is unfair to choose, violates a good faith agreement (they're there to sell you food - while it's not ILLEGAL for you to intentionally drive up, take up some time, and then not order anything, there's a good faith expectation that you are at least considering ordering when you pull up and take up time.) It's not a moral choice to do that. When the business shuts down over it, it's not the whole story to say 'their business model was inadequate is the problem.'
No one is saying you can't go get a snack during commercials, or you can't go to the drive through to see if anything looks good and not buy anything.
Wholesale totally killing your part of the payment for what you get is another matter.
They offer entertainment paid for by ads for you to watch, which have a chance - no requirement - to get you to buy things. You are making that a one-way deal where they spend money for you to get entertained and you give them nothing in return, which is not right to them and if everyone does it shuts down the business. The fact not everyone has a DVR doesn't make it ok for those who do.
