But that's a bad example, price discrimination for commodities is generally not legal, while discrimination for services is. Data is arguably a commodity (ianal, I'm not up to date on the law of this). "Tokens" are not.
In fact the law makes carve outs specifically for businesses that sell services to discriminate on price based exactly on how the service is used and by who. And they do it all the time.
Whether it's fair or not, up to you to decide as a consumer. If you don't like it don't pay for it.
