This is a good point, but this article assumes the questions are proffered in good faith. The example questions are explicitly in good faith.

There is the "just asking questions" method of casting doubt on something, often done by conspiracy theorists. It's a lot like the "Gish Gallop" - you could offer a lot of objections in good faith, but you could also often a ton of low quality, easily refutable objections in bad faith to run out the clock on a staged debate or some similar situation.
