Quoting Cyn: "Most of us don't buy services based on "give me these features and I'll pay whatever it takes." They buy them based on "I can pay $X and that will get me this subset of features, and I'll deal with it.""

That's what makes this a double-whammy. They are changing the specs into something else than what I signed up for (going from light use to something which apparently is appropriate for subletting to tenants, since that's what some people seem to be doing), *and* requiring me to pay heavily for this new product/feature set or lose what I have invested so far.
