No one is shitting on other people's choices. They are criticizing a major corporations choices to skimp on specs while charging a premium price. Specs that can't be upgraded and will absolutely lead to a shorter usable life. I find it odd that people get upset about criticism that isn't aimed at them at all. The only thing I can think is maybe they realize they were ripped off after putting so much money into Apple products and they need to defend their financial decisions. Even then I don't fully understand. I've purchased overpriced junk many times and don't feel the need to defend the offending company. Maybe it's because Apple has managed to make their customers feel like they're in an exclusive club even though everyone uses Apple products these days. A publicly traded company is around to make money and nothing more. They should never be held in reverence.

What is the obsession with shitting on people’s choices?

As much as people want to act like they are better than they were, say, 100 years ago, it's not really true. Humans are really just advanced monkeys running around and very few can actually surpass that nature.
