Something like kiosk mode does not cover it. It will have to be locked down to the point of uselessness. From the article:
"Only apps that have an approved youth protection program or a comparable suitable tool themselves will be accessible regardless of the pre-set age group."
“Only apps from safe places can be installed.”
Yeah, d’oh. Otherwise, massive loophole.
Yes, it’s a Nintendo-ify button for a PC. It’s opt in. And very convenient for parents.
And if my kid wants to install something, it can come and ask me. Like I had to go and ask my dad before installing sth (before I got my own Linux machine with 14).
Downloading Linux ISOs just became illegal for real this time.
Also, your lack of concern for any people or projects who may happen to actually be German is... disturbing.
