I could understand that interpretation. I just don't believe it's true. I think the best thing to say, if anything was necessary to say, would have been "This action is meant to defend the license, and does not constitute a judgment of the user that is violating the license."
I understand why someone would interpret Mastodon's statement that way, but I believe it is a misinterpretation and not what Mastodon meant. I don't have a doubt about Mastodon's meaning.
