@blenderdumbass >Linux, the kernel so associated with Free Software, was at some point proprietary.
It was proprietary in 1991 and was relicensed to the GPLv2-ambigious in 1992.

Linux was made proprietary again in 1996 via the inclusion of the first proprietary program disguised as an array of numbers.

>Visual Studio Code, their text editor from Microsoft is mostly Free Software
It's 100% proprietary, as binaries of vscode are released under a proprietary license that forbids reverse engineering.

They have separately released what they claim to be the source code under MIT expat, but it probably doesn't correspond (microsoft adding malware and spyware to the binaries would explain the part that forbids reverse engineering) and you have to go to vscodium to get binaries (as good luck working out how to compile it yourself), which seems to heavily rely on proprietary plugins.

>We can always tell the computer to do something ourselves.
Unfortunately, many computers now have digital handcuffs in them that disobeys the users commands, meaning they don't execute any program the user provides.

Intel processors after 2008 and AMD processors after seemingly 2015 refuse to execute free software BIOS's - they will only execute proprietary init software that passes a signature check.
