Depends on your definition of irresponsible.

Companies exist to make money so the most responsible thing to do is make as much money as possible. If breaking the law means you will make more money then do it.

See: a x b x c = x formula from Fight Club or Uber's entire business model.

Your assumption that we don't want bugs is probably why you are asking the question. Companies don't care about bugs, they care about losing money so if the bug doesn't cost money it's not worth fixing until it costs more than the fix.

I think this is actually very short sighted but that's just how the incentives align in our current system.

I make no claim to the philosophical implications of any of this.
