Yeah this discussion appears to have been hijacked by thinly veiled anti-union astroturfing. I would be highly skeptical of all posts in this thread. Many of the posts literally using the exact phrases commonly repeated by anti-union propagandists.
This makes me wonder if Silicon Valley is starting to see the writing on the wall and pay for disinformation campaigns in places where engineers regularly read and post. I know that there are people who share similar views to Peter Thiel within the software engineering community, but they are not the majority as you see in this thread. This is pretty shameful that this is what the Internet has become, a new medium to misinform the public. I wouldn't expect any productive conversation here.
