Are ISP bandwidth caps a threat to cloud computing? [Ars Technica]

Apparently, this a trend that will keep spreading in different markets. I live in Brazil, and found out this month that my cap is 60 Gb per month. Last month I subscribed to Carbonite (an unlimited online backup service), and uploaded 100 Gb to the Cloud. As I reached my cap, I was put on the lowest speed plan until the month ends, which is a really frustrating experrience.
With all these caps beeing set, I hope ISPs are reasonable and communicate these policies well. I really don't want to believe I should have spent the USD $54,95 that I paid on my Carbonite subscription on an external drive.
