A way to look at cable TV is like a buffet. Everything is paid for in advanced. In a buffet, you can eat until you bust and the restaurant would still break even with the food cost at worst. Most cases, profit. The rest of users always make up for the revenue 'losses' caused by a small set of anomalies. This double income from ads and data only happened because your carriers were allowed to get away with placing data caps on wireless. In some distance past, we used to get limits on broadbands too, remember?
