What weirded me out was it was being cast as a joint exploration effort when one of the members was charging the others. Would seem like a total grift, given the cost-cutting steps, if not for the owner/'designer' putting their own life on the line too.

Such deep sea submersibles are inherently a bit of an experimental industry, but even a cursory scan of opinions from others in that community seems to suggest it's seen as extremely not-kosher to put others' lives on the line with your experimental craft. Dude just seems to have been a bit nutty, and not altogether considerate enough of his own wellbeing or others'.
