I got an imperial administration law and can revoke dutchies without upsetting vassals.
Once I had a debt and one of my counts offered to by a dutchy title for 200 gold. I sold that, and few seconds later revoked dutchy. That vassal got +60 for granting dutch, and -60 for revoking ducthy, other vassals are not concerned… and I got 200 gold…
Free money? Do I miss something bad happening?

Assuming that the opinions time out at the same time, yes, "free" money for you.
Note that vassals do spend the money they accrue on improving their holdings, so your realm as a whole didn't change wealth. It's not an exploit.
