It does seem like Oceangate advertised in a misleading way, emphasizing claims of safety and compliance with safety standards. There’s also probably an unfortunate bias, of sorts, of “rich and powerful man saying something is safe in a confident and authoritative voice so it must be true”
There’s also a sort of morbid fascination and curiosity that comes from a situation this unique. I definitely agree that of course the sinking refugee ship should have gotten far more help and attention, but I think the “morbid curiosity” element is certainly part of why this got so much attention. The whole situation of paying a fortune for visiting the Titanic in a janky unregulated submersible and then vanishing underwater is…bizarre, and surreal, in a way that captures attention
