Layering vendor tools in boom times is great! Free offerings are generous, tools help enormously getting greenfield projects started. We can pipe tools together and with a shinny new front end we can bring a new product to market in days, maybe hours. We can even release our own tooling as frameworks, a nice career boost to developers involved.

Then comes the crunch times, and suddenly random vendors can rug pull your entire operation.

Yet we keep doing it every boom time because it's so easy!
