So it's not unmetered as advertised or am I misunderstanding that word?

How so? If they want to be relaxed about it, the terms can say that you can burst more (e.g. "you can use 500GB/month, and burst to 5TB for two months of every two-year period; we'll send you a notification email whenever this happens so you're not caught by surprise"). If they don't want to be flexible, they can mention the hard limit that they are going to enforce regardless of whether they call it unlimited without asterisk. Either way, the buyer would know what they can actually use and doesn't have to guess
