I'd guess less on "bad programming practices" and more "prioritizing development speed?" Mostly inline with your next point. We value getting things released and do not have a solid process for optimizing without adding new things.
Ironically, it was specifically the longer feedback cycle of long builds and scheduled releases that seems to specifically have given us better software?
Oh, I likely fully agree with you on it. I'm just pointing at the hazard that a lot of these practices aren't, intrinsically, bad. Rapidly getting something done is, generally, a good thing. I'm not entirely sure how to make it not the priority, but it does feel that that is the problem.
