Well if you want to leave you can do this either your Freedom or Youtube dashboard - personally I would recommend the YouTube dashboard as all you need to do is go to your status and features page and click the "remove access" button - this will tell Freedom you wish to un-partner with them and will take 30 days to do so (which is outlined and a term you agreed to when you joined) - there isn't a way to speed this up so you will need to wait the full 30 days. After that time you won't be linked with Freedom anymore, and will receive your last revenue from Freedom on the same payment delay as usual
