The community is up in arms because this essentially outlaws anonymous general-purpose computing, effectively forcing a national identification layer onto everything from laptops to smart TVs.

Discourse Is Not Going Closed Source After Cal.com closed their codebase citing the threat of AI vulnerability scanners, Discourse’s co-founder fired back with a vigorous defense of the GPL. The post argues that hiding code is a business decision masquerading as security, and that fighting AI-powered attacks requires an open ecosystem where defenders can run the exact same LLM scanners to find and patch bugs first.

The community was deeply divided over Cal.com’s decision to abandon open-source for its core codebase, citing the reality that AI vulnerability scanners have given attackers the blueprints to generate working exploits in hours. This sparked a fierce defense of the GPL from Discourse, arguing that hiding code is a business decision and true defense requires an open ecosystem where defenders can run the exact same LLM scanners. The underlying fear across these threads is that cybersecurity is transitioning into a “proof of work” token lottery, where defenders and open-source maintainers must simply outspend attackers using highly capable models like Anthropic’s “Mythos”.
