I think anything that mentions Apple in a negative light gets reflexive upvotes.
I use both Apple and Android ecosystems, so I’ll occasionally participate in normal user conversations about features, how-tos, etc. Posting anything about the Android ecosystem, unless I was talking about Samsung features I disliked using, is no more or less likely to get down/upvoted than anything else I post about any other technology. Using any tone more positive than a negative-leaning neutral when referring to any Apple product reliably collects a handful of downvotes, and often a negative comment or two. Same thing with negative sentiment and upvotes. I’ve never seen such a passionate dislike of a corporation among a small number of people. Even with famous brand loyalty rivalries like Ford/Chevy in the 80s and 90s it was more mutual. It wasn’t like 99% of drivers not giving a shit, .5% of Ford users being smug, and 2% of GMC drivers just being super mad at a product they don’t own.
I don't think you're wrong, but what's especially interesting about this is that up until just a few years ago, it was completely the opposite. Giving any criticism of Apple would get so many rapid/reflexive downvotes that it often killed the comment before many people even got a change to see it. I experienced it myself a number of times. Having been reading HN now for ~13 years (I lurked for years before starting to participate), that's been my number one dislike about HN is the complete inability to have objective discussions about Apple. At one point I even wrote a quick browser extension to filter out posts that had Apple in the title because it was so nauseating. Ideally the pendulum wouldn't swing, but instead would just settle in the middle, but alas that just isn't human nature.
