99%+ of people don't think like you and don't care about the distinction between code on the browser and code on the OS.
"A red herring is something that misleads or distracts from a relevant or important issue. It may be either a logical fallacy or a literary device that leads readers or audiences towards a false conclusion."
I don't see how my comment is a red herring. Computers are for running code. That's what they do. You said you don't want other people's code running on your computer. Bad news for you, that's all your computer does.
I definitely don't disagree with your statements, but I think OP meant more akin to "the web is not for running other peoples code". Ie, the web is for content, not applications.
This may not be what OP meant.. but it's something I can agree with to a degree. I love web apps, don't get me wrong, but I wish we had meaningful fallbacks for those who want content without features.
The more capable the browser gets the more people will turn off these capabilities. I love JS and the web, yet I have JS off by default! Mostly because it gets rid of a lot of crap, but I also don't trust every single web site I visit.
Computers are for running code as much as cars are for consuming fuel. They both need them to function in the manner that we currently use them, but that's not what they are for.
Both computers and cars exist to perform tasks that enable humans to do other things. It's possible to have a useful car that does not consume fuel and it's possible to have a useful computer that runs no code (hint: hardware's not just for mounting those pretty lights in your computer case).
