I find it amusing that people are only freaking out about Open Source Software when it comes to Claude Mythos. You do realise that LLMs can just as easily read binary files as source code, right? Sure, they'll be missing out on a few helpful things like comments, and some logic might be obfuscated/optimised, but I'd even go as far as to bet that this is going to be significantly more of a negative impact on proprietary software than it will to free software.
