From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

It's more the situation where the torrent/magnet string itself (or some peer connection) has some clever hack that exploits a bug in Transmission, allowing it to execute arbitrary code AS transmission. I'm skeptical there's a big risk of that, but the security theater kids LOVE sand boxing these days
It may be mostly "security theater" but it requires almost no extra effort and drastically increases the difficulty of compromise by adding privilege escalation as another requirement to gaining root access.
Has there ever been such an exploit? Given all other torrent clients I've seen just run as your user by default, is there something different in transmission over others that make it more vulnerable?
The point is also to minimize potential damages caused by a bug in the software. Just this year there have been multiple data-destroying bugs in publicly released software. If the app runs as a server it's usually trivial to have it run as a dedicated user, with just enough permissions to do its job.
It's just good practice, even though the risks might be low why risk it at all?
Not of which I'm aware. Transmission is more intended to run on a server though. You certainly can just run the local GUI, but it can run as a daemon on a server and then you can use a web interface or app, so its working more on a server v user app paradigm (Everything on a modern server like that is gonna run as its own user)
Not yet, but if every system was only protected against what already happened instead of also what could happen, we'd get hacked a lot more often!
