It's not hard to set in delays yourself if you want them.

You're missing the point though: these defi systems are mostly scams right out of the gate. They're designed to be exploitable by their creators.

They're also designed so that the exploits are plausibly denyable-- so while we can look at the long long list of anonymous created defi ponzis that vanish with everyone's funds via similar attacks we can conclude that many were intentionally designed that way-- attributing it for any specific one is challenging.
