Today has taught me that HN has a pretty fierce anti AMZN bias, and it shows. I have 4K+ karma, and am sharing my honest opinion and experiences working for AMZN for the last year. Next time, I just won't participate. This community has gone downhill pretty seriously in the last few years... No big loss.
If it speaks volumes, those volumes are more about this being a tech-industry biased forum than anything else. We don't really talk about the fast food industry and it's working ccondition nearly as much (though, even so, the whole industry is often used as a shorthand for terrible working conditions even when discussing other things.)
Your idea that the fact that HN talks about Amazon more than the fast food industry is anti-Amazon bias and not tech-industry focus is interesting, but not particularly plausible. (Especially given that plenty of that talk is positive.)
This might be one of the more tone deaf things I've read on HN in recent memory.
