Um, if you clearly describe what options A, B and C with their costs and consequences are and advice them to go with C but they go with A, then they explicitly did not go with your advice and can't blame you for their choice.

In the end, it's all business decisions. If it's something I don't like as a customer then it's to be infantilized.

(If you disagree then please don't complain ever again about LLMs refusing to help you reverse engineer a piece of code or explain how a virus works.)
