I mean it’s impossible on all computers.

Windows should ensure you can only use app-store and make it impossible to install an exe from online as example

MacOS even funnier. If I save a bash script I found online mac is supposed to refuse, unless I am using a vpn that is!

Everytime I see anubis I get happy because I know the website has some quality information.

You don’t have to do as they say but doing so lets you talk down to others who aren’t. So it’s a fair trade.

Who is using chromeos for that?

Redhat have very cool licensing.

They basically charge for commercial use but keep it free to personal users.

Redhat stock value reached at $190. (For perspective apple’s current stock is $200)
IBM bought redhat for $34 billion in 2019.
