I agree, but we are in the middle of an information war, which makes things very dubious and veils intents
For example, there are numerous channels on youtube who are devoted to setting up experiments to fail, in fringe domains.
In France we have a guy called Dumas who holds workshops in which they build, and tinker with, "sonic resonance boilers" like the one Peter Davey had (don't know the earlier genealogy of this invention). It made some hum on the french internet and, lo and behold, there were a couple dudes that made half an hour videos, showing experimental setups which delivered nothing -assorted with verbal mockery, of course-
Now why would anyone go the bother of making experiments the supposed results they deny, with the stated intent to disprove them, if they're not trying to force opinion?
Normal people don't spend their time studying flat earth, building mercury antigrav devices in their garden, or trying to channel the Galactic Ishtar Fleet, when they think it's complete bullshit. They do stuff that they believe in.
Also, as you said, incompetence is clearly not a proof of non-existence. "Look! I tuned it, plugged it, amp is on, and yet I can't play guitar. So, neither could Jimi Hendrix, and moreover nobody can. This is all wishful thinking!"
However, willful incompetence can pass for a lofty all-encompassing scientific knowledge, for the public. Long, pro-looking experiments filled with snide comments and, yes, filibuster-like avalanche of muddling details, will tend to have that effect.
As for Jack Cole his forum activity also gives a pretty clear image of what he's up to -consciously or not, always the same issue with groupthink: people pick up trends they are unaware of-
