I would not be surprised if the ads are placed at the current price tier, honestly. It wouldn't technically be lying; they're delivering a cheaper tier with ads, and a more costly tier without ads, just like they said they would! It's just that "cheaper" in this case would mean "cheaper than the new higher subscription tier", not "cheaper than the previous model".
