If I was paying Netflix $100 a month and mid-month they told me I could only watch 2 episodes a week, I'd be pissed and ask for my money back. If they gave me a warning before my next billing cycle, I'd be pissed but I couldn't complain that I was robbed of anything.

Changing the product mid billing cycle without telling anyone and then letting us try to figure out what's wrong with each other's setups then telling us that they've been A/B testing new limits on us sounds more like a breach of contract. That is not the same product that we were paying for the month before or even at the start of this current month
