Tbh, you aren’t wrong. I still keep getting anti-COVID memes and stuff from the lockdowns that’s kept alive by the out-of-touch rightwing clowns in my extended family. They keep all that stuff alive even though it’s been 4 years now and nobody remembers what it felt like.
Android runs an only slightly modified Linux kernel, and yet the OS requires much less from the user than e.g. Windows or MacOS.
Chromebooks run a bog-standard Linux kernel and the target audience is kids.
