Your logic is flawed. If developers don't want to develop for the N900, because they feel it's a dead end, then yeah, Nokia killed off the N900 with the Meego announcement.

That's what people mean and you know it. What you're doing is called "constructing a strawman", which means that when you have an opponent, you make up something that he supposedly said (that their N900 stopped working when Meego was announced) and then you ridicule that thought. It's a widely used debate technique, but also almost always frowned upon.
