I left a reply to another comment on this topic. To recap that here though, advertising is a non-technical medium generally not bound to literal correctness, especially when the claim is understood by any reasonable person to be an approximation, given that taken literally the claim is obviously impossible.
I'm not talking about literal or pedantic correctness here.
The antonym of unlimited is limited. You're using some impressive mental gymnastics to justify advertising a product with one word while providing the opposite.
If the literal interpretation of whatever hogwash the marketing dept is spewing is obviously impossible then I posit that the companies who do so are deliberately misleading consumers for profit. That seems to me to be an open shut textbook example of false advertising. But then neither my job depends on not understanding this distinction, nor am I overpaid lawyer employed to a company engaging in these patently fraudulent activities.
Bringing up false advertising demonstrates a clear misconception that I think is central to your misunderstanding. A claim of false advertising is predicated on the foundation that a reasonable person could have been mislead. But no reasonable person could be mislead into thinking that Google was offering actually unlimited storage, since it is clear to any reasonable person that such a thing is impossible. “Unlimited” is a perfectly acceptable shorthand for “unlimited as far as nearly all users can tell, interested users are welcome to read the full text of the legal contract agreement for more information”.
Olive Garden, after all, cannot actually provide you with “unlimited breadsticks” either.
