It is priced incorrectly, but that is intentional. You can't create a tiered paid plan for the whole world that fits everyone. You can't create nuanced extra plans to satisfy all the outliers. It's an bet to keep the customers and still having a good margin. Think of ecom, returns are a big struggle for any large company because they are unpredictable and subject to abuse, shipping fees are just an sophisticated guess to cover that cost. Not a subscription, same mechanics. The only thing here to criticize is, if it's a good thing to make everything a subscription and disguise the real cost.

I mean, you can. Electricity is already sold that way. Subscribers with uncharacteristic usage spikes don't get blackouts, they get a slightly larger bill, and perhaps get moved up a tier.
