Yes it should, so many places use it when they actually just mean "until our costs start getting overboard since we didn't account for more than 0.0000002% of people to use above X limits", or with so much fine print that they should be forced to make that fine print regular print.

It's a nasty tactic, and gives people the wrong expectations and in turn ruins markets to all start using such terms to offer "competitive" unlimited tiers.
