You love to see it!
I (with heavy LLM help) recently R.E. a golf cart motor controller which had a USB interface for programming, but only a crappy proprietary windows application, and it was super satisfying to see it hum attached to Linux.
What would be even more satisfying to see would be companies that were chill about this kind of work, instead of sending[1] legal threats[2] to people doing the work that they should be doing in the first place.
