Please don't be aggressive like this on Hacker News. It violates the guidelines and degrades the discourse.
That sentence has no information in it—it's just rude—so the comment would be better without it.
(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.
In some contexts, rough-and-tumble language is just fine and makes things more vigorous. Empirically, HN isn't one of those. Its system is too fragile. So if we want any high-quality discourse, we have to protect it. It's not an ethical injunction so much as a practical tradeoff.
I think the comment created worthwhile conversation. And I'm not sure it would be better off without it. Obviously you can disagree, and given your position perhaps my opinion doesn't really matter, but to say it has no information is just being dishonest, and I say that in the nicest way possible.
I see two conversations here. One is about users feeling betrayed by acquisitions and whether that could be mitigated contractually. That conversation didn't require abusiveness to be created. The other conversation is about who is being a fuckwad, and hardly counts as "worthwhile". Unfortunately, it is what such rudeness leads to, and it only gets worse.
Keep in mind that we're not talking about rudeness in general. We're talking about its effect on the already precarious balance of a particular optionally-anonymous internet forum. The argument here isn't ethical so much as empirical.
