Some of AP's argument (that others were doing it, so he felt it was okay) is essentially the estoppel argument. This was argued in the defense motion to dismiss (second one, IIRC). It was thrown out by the court but the standards for allowing a motion to dismiss differ from what will fly as a defense.
Hard to not see this as willful and knowing infringement, given the released emails and any number of statements on Twitter, etc., plus the KS information where defense says one of the risks inherent in the project is of being shut down by the rights holders.
A lot of what we are seeing also seems to go to how defense is trying to argue fair use. They may be going with a lack of actual damages or minimal actual damages, but that only matters and helps them if plaintiffs only want actual damages. By plaintiffs' attorney (David Grossman, I believe), by his own statement, plaintiffs are likely to pursue statutory damages. And then the actual damages don't matter at all.
And now here are a bunch of exclamation marks (!!!!!!!!!!!!!!!!!!) and STATEMENTS IN CAPITAL LETTERS. Just in case anyone adds more credibility to my statements if I use them.
If you want emojis, you're on your own.
