From the post, while it is hard to completely rule out the possibility that author did something wrong, they likely did everything they could to remove the suspicion. I assume they consulted all documentation or other resources.
Someone else's fault? It is unlikely, since there isn't (obviously) another party involved here.
Which leaves us to Google's fault.
Also, I mean, if a user can't figure out what's wrong, the blame should just go to the vendor by default for poor user experience and documentation.
Author's fault, Google's fault, someone else's fault.
