For #18, here's how my sneakernet software sharing goes: Windows: I copy the installer exe, or a zipped version of the software as installed to a flash drive. The person can then run the software from the drive, or copy it to their own PC. No Internet required, no outside connection called for.
Linux: after determining that they have the right distro type for the software, I have to walk them through either getting it from a GUI repository client, apt, pacman, flatpak, snap, or whatever other cockamamie thing it's on. They have to install it from the central authority - which is not sharing the software. It's suggesting that someone else connect to the Internet and download a thing.
If it requires the Internet to for a typical user to share software on media, your operating system is hostile to freedom.
