I could be ignorant but I like them, before LST/LRT platforms emerged if you were to stake, your funds would be locked, albeit earning interest or staking reward or whatever but now you can unlock liquidity using staked tokens and use funds as you please while at the same time earning rewards.
Yes it unlocks more opportunity especially to those who wants high yields and the only disadvantage it has was the launch of AVS that bypass Ethereum’s consensus layer. Probably it will just get ignored until there's a real problem that any user could experience but I believe devs will find a solution to mitigate it.
