What? Why does the ability to install software as an official feature mean the os/hardware supplier needs to support that install?

Since when has windows and any PC manufacturer ever done this?

This idea that allowing us to install what we like increases the burden to the provider is complete rubbish. It’s simply to lock them into exactly their infrastructure. So there’s no FOSS or any other alternative that doesn’t exactly follow their arbitrary rules.

I’m not sure I trust Temu Ross from friends.
