I hard disagree. The fandom is not that bad, sure some are way too passionate. But the fandom is way broader then those whom are vocal online a FOSS federated chat platform. Not everyone use Linux because they hate Windows or MacOS, some use Linux because they’ve seriously considered the pros and cons of each available OS and come to the one that works best for them in a day to day. Some are using it to revive old hardware Windows doesn’t support anymore so they can save a few bucks (and the environment at the same time). Some bought a Steam Deck and genuinely enjoyed it and decided to try Linux on desktop and like it, and so on.
Meanwhile : Apple fanboys are the way they are because “Apple daddy can do no wrong! my system is completely unhaxable! my brand shows off how rich I am! ew! omg! 🤢 is that an Android? POOR, WE GOT A BROKIE” at least with my personal IRL interaction with a few of them.
Like at least Linux is a community project that allows you to actually get involved in the development and contribute to it. But Apple has none of that, so it makes no damn sense to be that obsessed with a brand name just because it’s brand.
