>A flat fee, also referred to as a flat rate or a linear rate refers to a pricing structure that charges a single fixed fee for a service, regardless of usage.

That's one definition. There are others.

I'm sure you can use context clues to figure this one out. You're so close! Just put the pieces together.

There are no other definitions that‘s why they why internet flat rates got throttled instead of capped. Throttling is the loop bole because you paid for usage not for speed but flat rate with a cap is simply a lie.

What else would it mean?

That you are buying a bundle and it doesnt matter how much of the bundle you use you pay the same amount every billing period?

So if I buy entry to the swimming hall that allows me to be there for 4 hours but also allows me to leave earlier you would call that a flat rate?

I have never noticed there are people who interpret it that way.

If it allows you 4 hours total per month yea

That you are charged a single fixed fee regardless of usage.

Nothing about that prevents a usage cap.

A cap pretty much is the opposite of regardless of usage
