From this site, we have no indication that any actual person is putting any kind of good-faith effort towards trying any actual thing.

All we know is that a bunch of marketers are trying to find out: Given a certain amount of marketing effort, how many people can we sign up to a mailing list, and how many people can we get to pay a $99 reservation fee, if the product proposition is: You'll get a slick-looking "Developer-Terminal" (specifics to be determined) for $1.999. -- Based on that, they will decide whether they will lift a finger to figure out what the product should actually be, let alone put any resources towards developing it.

That's where the negativity comes from. They are eroding people's good will. Good will that is sorely needed when actual companies make actual products and need actual consumers to pay attention to actual product launches.
