I'm a hardware engineer:
The pitchforking on HN about "right to repair" issues. Frankly, those threads degenerate into what I'd expect on reddit.
To clarify, I support the problems trying to be solved but a lot of the ideas are just the wrong way to go about it. I've thought of weighing in, but the way some other dissenting commenters get beaten down means I self censor and move on to other threads.
