That will work until it very suddenly doesn't. The industry is awash in paid Internet-delivered advert-free services that suddenly got adverts stuck in them.

And no, if you're in the US getting a refund for breach of contract won't likely be an option unless your contract explicitly permits you to terminate the contract and receive a refund for the unused time. At least one court has determined that adding adverts to a contracted service -in the middle of most contract periods, rather than at renewal time- that was explicitly advertised as advert-free and requiring contractees to pay an additional like 3 USD per month to remove these new adverts wasn't a breach of contract or a price increase, but was rather a "change in subscription benefits" and was A-OK.
