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.

DO NOT download and install random programs from the internet. Not a deb/rpm file, not an elf binary, not an install script, nothing. Use your package manager or desktop environment's app store. At most use flatpak or snap packages.
Linux gets its reputation for not getting malware from the same place Mac does: It has a managed app repository where you get all your software from. Difference is Mac doesn't let you install arbitrary programs at all, while Linux expects you to know better than to do that. Someone who doesn't know what they're doing downloading Linux programs from random websites will inevitably hit one of the super rare Linux malware in the wild.
Even ignoring security issues, running an install script even from a reputable open source project's website can open you up to package dependency hell. And if you ever need to upgrade or modify it, you're in for a rough time because none of the existing tools built into your distro will help you. It's even worse than Windows when this happens because Windows at least expects for things like this to happen (because everything comes in its own installer and handles updates separately) and has UX elements to help non tech savvy users deal with their mess of apps, Linux expects anyone bypassing the normal package manager to know what they're doing and if you don't, it won't be a good day for you.
Since when does Mac not let you install where program you want? Are you thinking of iOS?
As far as I know when you download a dmg, the OS checks its signatures against Apple's registry and only allows installation if it's approved. The developer would have submitted the app to Apple (for like $100) for them to inspect even if it's not on the "official" app store.
Not a Mac user so please call me out if I'm just talking out my ass.
Right click, select "open."
In a better time, yes. These days it'll throw a warning that the application can't be trusted and offers to throw it in the bin. You have to run a command in the terminal now. Every time the app updates.
LibreWolf has updated?
Gotta do the dance again. Every. Fucking. Time.
I'm still running 14, has it changed since?
Does this still work to disable it system-wide?
sudo spctl --master-disableis it impossible to disable gatekeeper now?
Yes it's impossible to do it fully now :( but you can open programs from unapproved developers by going into settings > security > and select "open anyways". It's kinda a hassle when you like using open source software.
