The problem is that marketers exist to make you buy a product that you otherwise wouldn't. The hat of a marketer is not always that of a professional liar, but frequently enough that you do well to be wary of them. Much like police have no obligation or incentive to serve and/or protect anyone but themselves, marketers don't exist to solve any problem except selling the product. Any benefit you receive from interacting with them is just a side effect, which is why the conventional wisdom is to avoid them if at all possible.

What I'm trying to say is: Never Talk To The Marketers.
