I agree GoT fans are weird but come on, it's taken him a literal decade to finish the last book and it's going to take more with the next one. You don't have to bring up higher notions of entitlement or contract law to make the simple remark that the dude is slow and riding the gravy train that came with his early books (which took him much less to write, incidentally). Saying 'it's your fault' just makes you look like kind of a dick.
