A victory nevertheless but we have to consider that this is a USDC aka a stablecoin partnership.
Coinbase just getting more usage for their token isn't exactly more use for crypto. People that deal with stablecoins often buy them or issue them directly with cash. For instance if you have a Coinbase account even in Europe where there is no USD balances, you can buy USDC with EUR. This completely circumvents using any actual crypto like Bitcoin.
So the news are good for Coinbase and their stock, but not a guaranteed better market for BTC. This might even take away some usage from Bitcoin actually.
It is a victory because USDC is still a crypto and it will still allow the people who use it to explore other cryptos or opportunities in it. Another thing is that, Coinbase is a crypto exchange and there are still different cryptos that it supports other than the stable coins, so again those who deal with stable coins or fiat (Stripe) might still discover other cryptos later on. Don't worry.
This won't take away some usage of BTC because BTC is still different from the stable coins, I mean BTC is decentralized while stable coins are centralized which means there are less to no restrictions of using a BTC. Perfect to use if you're from a country that are strict, especially when it comes to payment methods.
