You don't need to fall back to a "default expectation" when usage is adequately indicated by context and by good faith efforts to interpret a statement in it's most reasonable form. Nobody confused it for a literal quote, nor did anybody feel it caused any misunderstanding, and those realities preempt any need to appeal to a default expectation.
In your case, I do agree that it was obviously not a literal quote. However, by the time I joined the thread, the topic had become more generalized.
Still, it would have been clearer to say something like "Exactly. And the response, which amounts to 'we're not trying to sell you a modem, we're just encouraging you to strongly consider buying a new one', is such a hair-splittingly asinine response considering the rather serious breach of trust posed by the notification system."
Also, for what it's worth, I do agree 100% with your argument there :)
@mirmir: Point taken. In the context of this as a more general subject, I think your observation is perfectly reasonable.
However, I think (1) few are as lucid as you on that particular point and (2) whatever the merits of this as a general debate, and I think there is some merit, I think the question is whether this norm improves conversation in a thread like this. I think it was invoked frivolously, spawned a long, 50+ comment chain, and it didn't clear up any of the confusion that it seems like the norm is supposed to be designed for.
