Product and project managers can have similar issues of perspective as engineers, chasing trends in the industry or losing the forest for the trees (feature checklists, etc). But, yeah, having devs talk directly to customers can be problematic. If you give a customer a direct line to an engineer, sometimes they can monopolize the engineer's time (they feel they can leverage an "inside" contact) or skew their priorities. Having engineers work closely with tech support is a good middle ground, such as by fostering 1:1 relationships with support or even fielding tech support tickets themselves (tech support tickets have more finality than, e.g. sales support issues). That way they can get a broader perspective on pain points and potential new directions. It can really help refine a product beyond what can be achieved by lobbing feature and bug tickets over a fence or through formal group meetings (which often can be either too structured or too chaotic).
