The period of renewal stays with the domain name so it's not like I'm going to lose the money I paid to GoDaddy. If I change my contact details in preparation for a domain name transfer and GoDaddy locks me out out of transferring it for 60 days, what's to stop me from transferring it on day 61? If it happens to overlap with my renewal with GoDaddy then all I have to do is renew the domain name for one year with GoDaddy and then transfer it when the lockdown is over. Nothing is lost here. It might be inconvenient but they're not bilking anyone out of any money.
