I think that both words 'author' & 'authority' are related...
Perhaps, initially. Someone that created something, was the only authority that could say if others used his invention correctly, or not. Or was responsible of any wrong use of his creation.
Then, when she sold her creation to other, the authority should extend to the new owner. But, in reality, depending on the complexity of the creation, the last word should belong to the creator.
Today, we might have missed the original point. And anyone that owns anything pretends to be as the creator. Extending eternally the rights of something that they might have bought but that they might not understand.
But who cares? It is now, only money...
