It is good that DeFi is being used in new areas that already have many users and are popular. This will more popularize cryptocurrencies and attract many new users to the DeFi market.
But there are also a lot of defi projects that are not really targeting what it use to be.
Everyone has to be careful with those defi projects and if they just want to earn passively, you can choose to have staking coins and just do it on your own without depositing it to any platform.
