“Writing for his fans” is another way of saying “writing for a group of sycophantic and undiscerning fanboys”.
And anyone could defend anything with that excuse.
'I thought that post was pretty shit, to be honest Default.'
'I knew you would. But I wrote it for the fans.'
'What fans? I don't see any fans.'
'No, but - okay, there ARE fans, right.'
'Maybe these "fans" only exist in your mind.'
'Shut up. There are fans. There's a hardcore fanbase here. They're all lapping it up, oh they can't wait for my next one. I must keep making films to appease them.'
