That's its usage.
Every one of those "apps" is usage on Ethereum, everything from trading (Uniswap, think of it as a Coinbase competitor), loans (Maker), to mutual fund like assets (Yearn).
It's hard to convey in a few words how much better buying a house using Maker/Eth was compared to going to a bank. Everything about the process smashes the traditional system.
Yes, Ethereum has been working towards several long-tail projects for years. I think it's more important to distinguish that nothing good or important has come of Ethereum though, and that it is NOT money, and it is not a safe currency. The blockchain is fraught with front-ran txs, the mining is very centralized, and all projects atop ETH suffer dependency on it's success. The blockchain is growing very large which leads to further centralization on very expensive customized equipment. DeFi is a buzzword that means little but "super alpha experimental money leveraging tools" and financial instruments on the cutting edge. Ethereum is Dave & Busters tokens in comparison to Bitcoin being real money.
I mean, Ethereum has the second largest marketcap of all cryptocurrencies and it feels like 80% of the research & development either comes from Ethereum directly or close-by ecosystems.
To say that Ethereum is Dave & Busters tokens when compared to Bitcoin is funny, since every single cryptocurrency is magic internet money anyway.

It's pretty bad that Bitcoin still hasn't started working on it.
They would like to switch to proof of stake and plan to do so next year.
