I’ve never found myself in any online community that meets that description. Certainly not HN, and HN hardly seems big enough to have Apple fanboy niches that you could accidentally find yourself in.
In the heyday of Steve Jobs’ Apple there was certainly a lot of praise here, but also constant prominent complaints about Apple being overpriced, or not open enough, or too litigious, or having too many fanboys.
I’ve seen way more complaints about Apple fanboyism than actual fanboyism. I’m genuinely curious how you could find yourself in one of those communities by accident.
