I've been using Arch for about 15 years or so, and yes, I build up cruft... in my home directory ;-). The system itself is remarkably good at keeping tidy. The one spot to keep an eye on is /var/cache/pacman, as that's where it stores every package you download before installation and it won't delete it without you asking it to.
Any new config file will be saved with a .pacsave extension, so you'll want to keep an eye out for those, but that's basically it
It's purely financial. We make a lot of weapons and we like selling them. The best customers are the ones currently using the weapons, since that lets us test them in the field and guarantees that they'll want to buy more since they've just exploded the last order.
I honestly don't think they care who the weapons are being used against, and the "antisemetic" label is little more than a shield used to deflect criticism. If the bombs were being used by Saudi Arabia to level Israel, I'm confident that the political apathy would be similar.
If you want them to care about more than that, they have to believe you'd vote for a party opposed to selling weapons to genociders, but instead of Green, the country voted Labour with their stated unshakeable support for genocide so... we get who we vote for.
Actually, tutorials like that are a big reason that I don't want to switch. The first steps are things like:
Install these fonts that only work in a GUI environment
Install these programs straight from GitHub without your package manager
...and all I hear is: "this stuff isn't ready yet" and "I'm going to be staring at Unicode glyphs the next time I have to tinker outside of my GUI".
If I can't easily and securely install a shell on every environment I use as I don't want to be constantly context switching, then I'm going to have to stick to Bash.
Honestly, the only btrfs feature that interests me is the snapshotting, as the current state of my backups is rather sub-par. There's just a lot of inertia involved in adopting it when ext4 Just Works™. Maybe next time I install a new system I'll give it a shot.
As for zsh, I rather like the general "intelligence" I see on others' machines: the way it autocorrects typos, draws a navigable menu for tab completions complete with colour highlighting... it looks lovely. I've been a Bash user for 25 years though, and muscle memory like smashing the tab key to get what I want is a hard habit to break.
I feel like these are rather tame choices to be honest, though I can't recall anything specific. I just remember hearing him speak in the House years ago under Harper and thinking: "What an odious little man".
Rather than sifting through controversial news headlines, they'd do well to sift through video archives of house debates. I seem to remember racist dog whistles and some pretty terrible things said during the Conservative push for voting "reform" and that Muslim snitch line.
Here you go.
