Sorry, let me clarify. It's always possible to claim anything. I meant that the claim is too weak for the SSPL to create that threat.
It's obvious that several people disagree, but within this thread, conversing about this article, we should expect a bias to see things that way. I hope you'll stay open to being convinced otherwise. The SSPL has been submitted for review to the OSI, and this issue is one of the points of discussion that we're listening very closely to.
