As opposed to sharing that type of information to mock others? Using a questionable source(at BEST) to dispute other's facts?
I quote the King and I, "A puzzlement"
"And it puzzle me to learn
That tho' a man may be in doubt of what he know,
Very quickly he will fight...
He'll fight to prove that what he does not know is so!"
So people don't share info because they can't or maybe it tickles them that a particularly difficult person makes a habit of fighting them just for the fun of it.
Get over it.
"Secure" men don't need to rally others to support their personal fights.
