The question is, if he’s a cook and conspiracy theorist, why would they arrest him? I never heard of this person before and his claims sound a bit off but whatever.
The only reason you arrest someone, either they did something wrong and you have convicted them of a crime or in a communist regime, because you want to silence them.
It can’t be option 1 because that would imply he does not have freedom of speech, which so many western countries pride themselves on so it must be option 2, the question is then, why silence someone that is not telling the truth, if it would be easy to disprove as so many here state, I note they haven’t brought anything as far as evidence. So whatever he says must not be capable of being disproven, aka, facts.
