So happy to see Discourse not only staying open source (which I never doubted), but also deciding to take a stand here. 
I don’t mind Cal’s decision, it’s theirs to make, but the whole spin-doctoring is extremely frustrating.
One thing AI code generation and exploit hunting has taught me is we’re still fighting the same bad but popular ideas that executives have held since the dawn of time. In this case the “security by obscurity” argument against open source.
