If it was just him and his buddies getting on this sub and doing dangerous voyages then I see no problem.
But to ignore industry experts and invite paying clients onto your ultra-dangerous submarine, well that's not a good look.
The simple fact that there was no possible egress without outside assistance should have been reason enough to scrap the design. With constant safety issues on what seems like every single one of their dives, I'm actually amazed that the Titan didn't kill someone sooner.
When your feed stops being broke I'd guess.
