I think everything on this page is about encouraging reasoning rather than just collecting facts. If someone takes each one as a truism and blindly follows it, then yes, it would turn these mechanisms (which are supposed to help us identify and fight our own cognitive biases) into just another form of cognitive bias. That's why they're not laws, they're just handy patterns to help us reason about things that we see every day. I'm not sure what you mean by using them as tools to avoid reasoning- they are explicitly meant to help with reasoning. I don't know what sort of reasoning could be done without incorporating any sort of logical frameworks at all. That's all this stuff is, tools to aid reasoning by identifying common patterns and antipatterns in thoughts and perceptions about the world around us. Anyone who treats these ideas as absolute laws rather than occasionally (frequently) useful abstractions is doing it wrong.
