My software hand trowels don't get randomly totally wrecked by some fresh grad UX guru who decided that they needed to rework everything to justify their employment or because they felt they urgently need to chase the latest design fads, because the old ones are so last year. Most tools in those other professions don't have that problem. Once you buy them, they're generally static. But yeah, your point about devs being hilariously stingy and not valuing their time is pretty spot on. I just don't think that's the main reason they don't want to buy commercial tooling.
