Are people just aching to constantly blame poor people for moral and ethical failings, and not the grifters who prey on them?

Yes. People definitely blame victims all the time. There's no way LLMs, their proprietors, designers could be practicing dark patterns, marketing gimmicks and security shortcuts to convince people to shot these guns as often as possible...even when, they point them at their foot.

This grift is deep and wide and you may want to re-evaluate why everyone is so keen to always blame victims for technology, society, and business marketing.
