He spoke of a clown industry. That means the industry as a whole. That includes, but by far isn't limited to, the devs. Which of course have to operate in an environment, most of them set by their employers. And of course, responsibility scales with the position in the hierarchy. So yes, to a large part it is the management setting deadlines, budgets, staffing and planning allowing for technical soundness and of course safety and security.

But also every developer has a responsibility. At least not to promote any technology which is part of the problem.
