a) It is not against AdWords TOS provided you have permission to use their trademarked terms. Which Apple has since in the Developer agreement [1] they have been assigned permissions to use logos, trademarked terms etc in marketing material.
b) Google is incentivised to tackle abuse within their system. It's ridiculous and baseless to say otherwise. Lack of integrity in an ad marketplace very easily can translate to lost dollars. But unfortunately with spoofing being trivial it's simply hard to detect and manage abuse.
c) There is no regulation that will prevent this. App developers have signed a legally binding contract.
