I nominate this thread for “sketchiest question on Lemmy”.
In all seriousness, at the end of the day, the legal side of this hasn’t been thoroughly tested. I would personally err on the side of caution and abide by the stricter of the laws between your country and your instance’s country. If either prohibit criticism of government, you may run into issues depending on the combination of countries. It’s safe to assume instance owners don’t have a gigantic legal fund either, so they may be more easily forced to give up access logs which could be used to trace you.
There’s also the forever unsaid “don’t be a dick” clause. If a country prohibits some form of speech, don’t intentionally try to get instance owners in that country in trouble.
I switched to a Mac a couple years ago but I'll always at least keep a Linux VM and a separate Linux laptop just in case.
As for why, generally speaking, Apple puts a lot of really, really good work into making a machine that feels immediately productive with little fiddling around, they're ahead of the pack in some ways, and for advanced stuff it's "good enough".
My reasons:
Device restoration - Restoring a Mac is just impressive for how little effort it requires. If someone stole my laptop, I can drive 15 mins to an Apple Store, buy a new laptop, point it at my NAS, and be back running in an hour or less to exactly where I left off. Similarly, If I buy a brand new laptop, copying data from the old one to the new one is incredibly boring -- in all of the right ways. All apps/info/config/etc gets moved over. No weird quirks or workarounds or anything needed.
M-series laptops - At the time, there were no other good options for ARM CPU laptops, especially ones that can be spec'd to 64GB of RAM. The M CPU laptops are crazy fast and efficient. I can literally use my laptop for 9-10 hours in a day going full-hardcore, and still have juice to spare. Yeah I know Asahi Linux works for the most part now, but I don't have time anymore to beta-test my main box.
Adequate Unixy bits - The terminal does everything I need, the utilities are fine. I use Nix (and some Homebrew) to maintain various CLI tools.
Software - I wanted to save this for last since everyone quotes this first. I wanted to meddle with music and Ardour doesn't really scratch the itch the same way Logic Pro does. Another example: as bad as the Mac version of Microsoft Office is, it's still far more nicer feeling than LibreOffice and requires much less work to get a good looking presentation/etc. out the door on a time crunch.
