Millions of Windows power users are accustomed to bypassing SmartScreen.
A macOS app distributed without a trusted signature will reach a far smaller audience, even of the proportionately smaller macOS user base, and that's largely due to deliberate design decisions by Apple in recent releases.
The point is that any filesystem can be chosen as the OS’s root.
The root of all other filesystems - there could be multiple per drive - is where you tell the filesystem to be mounted, or in your automounter’s special directory, usually /run/media, where it makes a unique serial or device path.
It's a nice sentiment. The companies with the integrations are the ones that could take it back, but they don't have the incentive to break legal agreements and share with the world.
Meanwhile the creative output of humanity is distilled into black boxes to benefit those who can scrape it the most and burn the most power, but this impact is distributed amongst everyone, so again there's little incentive among those who could create (likely legal) change.
“Intellectual property” is a propaganda phrase that deliberately confuses copyright, trademark, and patent law in order to create the illusion that ideas can or should have owners. (See https://www.gnu.org/philosophy/not-ipr.en.html)
I recommend specifically referring to the concept at hand, in this case copyright.
Personally I disagree, as the models themselves do not contain any material which can be considered a copyright violation, the value of scraping the open web is easily apparent, the ability to prevent scraping wholesale - even given the legal framework to disallow it - seems dubious, and lastly because the collective potential harm caused by restricting just one or a few of the more arguably more ethical nations from this technology pathway is a known unknown, and possibly a very large one at that.
Smartphones aren’t servers, but they run tons of services that interact with the surrounding world.
Bluetooth, WiFi, etc…
The kernel also still plays a vital and security-meaningful role in processing calls from applications.
Running an out of date kernel could mean strangers ransoming your data, or could mean an attack becomes persistent and starts logging and uploading through reboots.
Running an out of date kernel often does not result in this, and that higher level security matters first.
However, the kernel does have an attack surface through those higher levels, and pwning the kernel still means something.
Those datacenters are running LTS kernels with minor versions updated, or have security patches backported, or have far more limited connections to the world than your phone — only one protocol, one port, one service, for example.
