(Because of HN's lack of comment notification system, I had no idea it was so controversial until I happened upon it again just now.)
Its significantly positive score does suggest to me, though, that there is a lot of sympathy for my position, and the angry way I stated it. In fact, it's one of my most upvoted comments. (And assuming it's received a significant number of downvotes for being unnecessarily rude, I suspect it's my most-upvoted comment of all time, in gross numbers.)
The claim that I'm complaining about is basically outright fraud, as far as I'm concerned -- they're advertising their startup as being different from other services, on the basis of having a quality they have absolutely no ability to promise (that of being guaranteed not to terminate service out from under the users without warning.) The only mitigating factor is that they are almost certainly misleading themselves as much as their users. Whether this is noble, I leave as an exercise for the reader.
