That’s a bit reductive. Macs are solid native mobile dev machines as well, with a good number of even Android-only devs using them. Lots of dev houses in the US use them for backend work (including Docker, despite the performance penalty), and the FreeBSD devs have been known to use them too.
The whole "this machine is more stable" and "my anecdotal opinion is x/y/z" nonsense is a non-starter for productive conversation comparing the systems. The upthread comment was warranted to call them out on Apple fanboyism; their statement was nonsense and exclusively backed by their personal experience. I've talked to enough "serious developers" to know that there are no perfect operating systems, and pretending like any one of them is king is just hubris incarnate.

Make up your mind.
If you're a webdev or hipster programmer chasing the most lucrative Web3 gigs, sure, buying a Macbook is probably the kind of status symbol your peers will respect you for. At the end of the day though, they're all just tools with different uses. If you can use an ARM laptop for day-to-day work, then don't let anyone stop you from doing it.
What people dislike is your "every serious developer owns a Macbook" claim. It's the sort of thing you hear from West-coast Google engineers who look around their office of L3 Javascript employees for a sample size before posting a comment. It honestly doesn't reflect the myriad of programmers you'll encounter in the world; some of the most productive 10x developers and "security people" I've met are using systems that even I would consider asinine, like NixOS, QUBES, Whonix or OpenBSD. I don't knock them, though. We judge hackers based on their skill, not their salary range, clout, and least of all by the laptop they have in their backpack.
