Back at the end of 2018, a defunct Swedish app developer sued Facebook for the changes the company made to its app platform. As detailed by Cyrus Farivar (then at Ars Technica), it appeared that the lawsuit was somehow connected to the more high profile case filed by the developer of a sketchy bikini-spotting app, "Pikini," Six4Three. At issue was that after Facebook realized that various apps were abusing the access the Facebook platform gave them to suck up data (a la Cambridge Analytica), Facebook drastically scaled back the platform and changed overall directions. Six4Three is fighting to argue that somehow Facebook owed it to developers to keep its platform open.

This other company, Styleform IT, seemed to jump on board with a lawsuit that had some striking similarities to the Six4Three suit -- including sharing some of the same lawyers. Either way, Farivar alerts us to the latest in the case, which is that Facebook has filed an anti-SLAPP claim against Styleform IT, arguing that its attempt to sue Facebook and Mark Zuckerberg over the company's moderation choices violate, first, Section 230 of the Communications Decency Act, which allows for Facebook to choose to moderate its platform however it wishes, and that the lawsuit itself is predicated on a 1st Amendment-violating effort to stifle Facebook's expressive decisions.
