Well in some (common) circumstances it actually makes perfect sense.
The most common daytime fourlegged predator in most areas is the dog (own, neighbor's, or stray). While *some* dogs will jump or climb, *most* will not bother. Thus having a dogproof fence, even if the TOP is not dogproof (be it open to the sky, or netting, or chickenwire), really does have a lot of value. And chickenwire is just not dogproof.
If you have a privacy-fenced yard and are POSITIVE that your kids or neighbors or meter-reader will NEVER leave the door open nor anybody's beagle dig under the fence, then I can understand not sweating the daytime-dogproof thing.
But for most people, it is a significant issue and thus it makes a lot of sense to use something stronger than chickenwire EVEN WITH an open-topped run
