I disagree, I think 'Bug' is a risk-shedding weasel-word. It's meant to shift blame away from the technology and its creator (multibillion dollar AI companies etc) in a way that doesn't hold those actors accountable or responsible for the outcomes. In any other software it would be an error, regression, hallucination. And in a human process it would be at ~least something someone would call 'bullshit'.

You made a lot of clams about how it intentionally shifts blame, but none of them are supported.

Do you really think accountability would be meaningfully different had they been called bugs?

Why are you so confident it is intentional? My understanding of the history is that it was a technical term among researchers long before it had any public mind share. It's popular because it's and intuitive for most people, not because there was a concerted effort hooked up by some PR and legal team.
