Honestly not a bad reason. Although this seems unprofessional for them, since they could just as easily do this on another exchange? Also, do you really think that they've held their ETC this whole time?

1) People already know the name "Ethereum" 2) It's actually used quite a bit 3) They already had the data infrastructure since it's no different to host than ETH 4) It's not a scam (like most BTC forks are) 5) It warms people up to Coinbase growth prepping for ERC-20 token support.

It's an alternative to Ethereum in the event ETH is labeled a security.

2. What is ETC used for? An overwhelming majority of businesses are using ETH over ETC because it's being developed by autistic skeletor 5. Why not just come out with ERC-20 support? Also not difficult for them (see 3)

This has nothing to do with the SEC.
It was a move to please Barry Silbert, a big Coinbase shareholder who holds a huge stack of ETC.
Coinbase always chooses the path that is just an inch from being blatantly unprofessional while making them the most profit. Remember when BCH was added?

Its name is derivative of etherium 100% only reason
