it's not 'somehow'. In Claude Code, type /memory to be able to edit the memory files if you've turned that feature on. If you're a biochemical weapons researcher who has somehow managed to both turn the feature on and fill up the memory with attempted biological weapons research, you can (a) turn that off or (b) go and edit the files to remove objectionable lines of attack.

Regardless, the number of innocent biochemists who have been hamstrung by Fable is essentially zero (but somehow they have all shown up on Hacker News to decry Fable), and the number of non-innocent would-be-biochemists who would love to have unrestricted Fable help them with their non-innocent biochemical research is absolutely greater than zero.
