We take no cut with ocdb at all. The argument that you are getting steem you weren't supposed to get, well, the delegators would've instead delegated to a normal bid bot and gotten their ROI that way instead while enriching the owners for doing pretty much nothing. This way a whitelist of people get the 10% profit instead and maybe some day they'll start curating and using it for something better. Easy steem earned usually means it easily ends on the exchanges so I'd rather help distribution which is important for our currency.
