Edit: Made a separate discussion for the question here: Can you sell the work on refurbished/maintained computers with unmodified Fedora Workstation?
Is it written down in legal-text that one can’t simply install a Linux distro on a computer and give it to someone?
Technically if I offered a computer repair service, I’d be charging for setting the computer up and making sure it looks good (BIOS update/settings, hardware stress test), but not charging anything specifically for the choice of OS installed.
Like Windows I can understand (assuming the computer doesn’t have a key in UEFI), but FOSS Linux distros are free? The user would have an unmodified distro and can grab sources for GPL.
In Fedora’s case I would probably install it, and at the end of install I’d power it off and that’s it.
Although in that case I wonder what constitutes a modified install? I do Custom partitioning without Btrfs and LVM; it’s not default, supported by the installer, but does something like that count as a custom change?
