I think you do not hate corporations just for the sake of it. There is money in the outrage business. Every movement can be sabotaged by people who have their own self interest t the forefront. It is easy to hide bad behavior under emotional issues.
It's fair to assume that every firing is done for a reason/as a result of a problem, and having evidence of the reason being immoral is important if we're going to be a responsible "court of public opinion".
HN as a whole only very recently started to "beat" on Apple. Before 2021 it was a lot of "well maybe there are two sides to Apple curb stomping both devs and users."
My direct experience is that there is a lot of skepticism about Apple on HN, much of it warranted, some of it (in my opinion, obviously) careening into unwarranted cynicism. But my observation is that comments critical of Apple that are most likely to get downvoted are ones with a clear subtext of "anyone who uses Apple products is an idiotic corporate shill who doesn't know anything about technology and it is my solemn duty to preach the anti-Apple gospel." If you come in with a chip on your shoulder, people will be inclined to knock it off.
Just another anecdote - I regularly see commenters decrying the walled garden, etc. always with the addendums that they’ve abandoned all Apple products, don’t use Google search, and use Linux on their Thinkpad instead of Windows. I notice so often because I have a lot of doubts about the veracity of those statements.
I've never seen a struck out anti-Apple comment that didn't spend the majority of the comment preemptively complaining about downvotes and disagreement.
FB, Goog, Amazon, MS fire an employee -> they are terrible companies.
HN’s biases are infuriating.
Replace Apple with Facebook or Google and everyone will have their pitchforks out.
