Right, that's governed by your contract with Coinbase, and is the service they offer.

No, everyone controlling a BTC wallet is now also controlling a BCC (or BCH, I've seen both used as the abbreviation) wallet with an equal number of coins.
I'm guessing rights to coins on alternative chains that Coinbase ends up controlling due to BTC forks are not covered in your contract with Coinbase.
