I'm wondering what any lawyer here on HN has to say about how much of a claim WP Engine has against them being banned from the WP.org plugins repository. My layman's understanding of the law tells me that they have no claim whatsoever; you can't assert rights from something that's provided for free, let alone something so expensive to run. The only claim they may have is related to it being used as a means to extort them, but that is a separate issue.
