What the hell are you smoking? What "narrative"? "Bait and switch" has a definition:
Dictionary.com
You're claiming MVPDs who raise their rates after a year (or presumably 2, 3, 4, or however many years) are using "bait and switch". Let's not even get into the fact the discounts expire after a set amount of time is readily available before anyone signs anything. The fact people don't read that is on them. MVPDs aren't "switching" anything. You still get the exact same goods, for the price advertised, for the time frame advertised. There's no "bait and switch".
If you sign a 2 year contract and the rate rises after the first year, I'm calling that bait and switch. If you don't want to have a conversation without cussing at me, then feel free to use the ignore function
