Here's a basic rule of thumb I recommend people apply when it comes to these sorts of long, contentious threads where you know that not every person showing up to the conversation is limiting themselves to commenting about things they understand and that involve some of the most tortured motivated reasoning about legal topics:
If the topic is copyright and someone who is speaking authoritatively has just used the words "copy written", then ignore them. Consider whether you need to be anywhere in the conversation at all, even as a purely passive observer. Think about all the things you can do instead of wasting your time here, where the stakes for participation are so low because nothing that is said here really matters. Go do something productive.
