as a computer moves ever more towards a white-label appliance with a single purpose, the act of "installing" becomes more and more alien. It sucks, but a majority of the computer-using population cares not for it, and only want it to work. Think washing machine - have you ever seen people want to install apps into their washing machine?

You can call of whatever you wish. But how did loading from any untrusted source work out for the average consumer for the last 30 years? Viruses, malware, ransomware, etc?

HN users have been whining about not being able to side load on iOS devices for years. What they really seem to want is to force the app stores to carry anything.
