Yes and no. It’s just that no one has bothered to make the page for one; you’re free to do so. Your accusation of deletion implies that there was a page that was deleted. That would be a bias, but it wasn’t the case. The page was a redirect that violated the rules.
In other words, there’s a bias in the editors to not make it, but there’s no malicious bias that deleting an actual article would imply.
