Its exactly the kind of thing I expect from when people in tech go try do something in other sectors without an adult in the room.
Thoughts on the "lessons" (out of order, deliberately).
Lesson 2: Word salad that basically means "we hired people who didn't know what they were doing, and expected the performance of professional tradesmen to just magically happen".
Lesson 1: see lesson 2, but with additional process issues that anyone with any construction experience could have warned you about, and chronic understaffing to keep a lean headcount.
Lesson 3: basically they decided to ignore tried and tested business strategies for growth and wing it instead. This didn't work.
Lesson 4-6 mostly, again, are poor business planning.
