This has already been explained, but I will repeat it. Note the word "purposely" in the hoax rule. That means there is an element of intent in the rule. So if one honestly believes X, even if they may be wrong, and they post X, that is not a violation of the hoax rule.
So the hoax rule is being enforced as it is written.
What you are asking for is fact checking, and that is unrelated to the hoax rule.
Why not amend or abandon the hoax rule as currently enforced and interpreted?
Why not explicitly state that it applies to, and is to be applied to threads relating to Apple products and nothing else?
As currently interpreted, it makes a mockery of the site, and, as others have already pointed out, it fails to meet the (already rather low) bar set by platforms such as FaceBook and Twitter.
Nobody is asking the mods to become "fact checkers", but inferring intent is at least as arduous a task as checking facts.
Indeed, writing as someone who was a professional historian in a previous life, I would argue that inferring intent - or attempting to read intent from a post, or letter, a diary, or source - is arguably an awful lot harder than mere verification of facts.
Something either happened, or it didn't.
A fact is either true, or false.
But attempting to infer intent is a challenge that the most empathetic person on the planet would find hard to meet.
However, in attempting to meet it, I would respectfully submit that the use of the word "purposefully" in this context is somewhat disingenuous, for inferring intent, is, at its best, in the absence of a declaration proving intent, is both subjective, and very difficult to prove.
