These days I've been looking into LST and re-staking again. To be honest, the returns don't fall from the sky: part of it is the "salary" from validation/MEV, and more of it is actually using the same collateral to give others a security guarantee, with others giving you some incentives/fees as rent. It sounds pretty attractive, but the risks are very real: if the smart contract has an issue, it's not just a matter of the token price dropping; on-chain, it could be stuck or penalized directly. The "shared security" model of re-staking relies on the underlying project being active; if it's not, it’s just propped up by subsidies, and the compounded returns can look like a matryoshka doll, so disagreements are normal.
