The DeFi protocol distributes tokens to their users, and has sparked a frenzy of "liquid mining". Take the most famous liquid mining project as an example: Compound Finance. They send the protocol token to their depositors and borrowers. Compound Finance said that this is for more decentralized governance, and they hope to empower people who frequently use the protocol.
People are not stupid; we all know that Compound is making money: about 10% of the interest paid by borrowers is collected as a reserve fund, and the Compound government can easily use it as income from the agreement itself.
