It is super easy to say "Well, business owners have mechanisms to correct false information", but this requires the business owner to regularly check not just Apple Maps, but every such service (which he might not have even heard of), find out the process to correct the information on each service that has it wrong, possibly prove to these services that he is who he says he is and is also the owner of the business (potentially subjecting himself to phishing attacks). And, if the onus is not on those businesses to not publish false information, even after all that, they could just ignore him. Even if successful, if these systems are not well-designed that information might be overwritten with the next update from whatever source originally offered up the false information. No, the publisher doesn't get to be off the hook because "it's hard to be accurate." My guess is that Apple et al have contracts which indemnify them and if he is the ultimate source, he's already signed away any right to damages for information he provided (and maybe information he didn't).
