why shouldn't Wal-Mart be allowed to choose which customers it sells to on any grounds whatsoever?
Because we live in a society with rules. Although it's very indirect, ultimately those rules are chosen by the people (all the way back to the people that chose to ratify the Constitution). And those people don't want Wal-Mart to be allowed to do that.
There are many users who view Javascript as inherently evil and think the Web would be better off without it.
How many, really? Are these the same users who think the web would be better off without any advertising? Just a guess, but those users probably don't weigh heavily in google's priorities.
Its *my* PC and should only be running open source code which many eyes have looked at (not true for a majority of Javascript loose in the wild).
If you apply that to sandboxed, interpreted languages....you might as well also apply it to html. Html, while not really a programming langage per se, does instruct your computer what to do. If the browser has a bug, malicious html can cause harm to your computer or compromise your privacy. What it the difference?
The whole comment about the number of users not mattering must be bupkus.

When a web developer speaks in terms of which browsers they do and don't support that is a direct indication that they don't understand even the most basic and fundamental concepts of website design.
Well, with the exception of IE6. I wouldn't fault a site for not caring anymore if their site looks crappy on IE6.
when you browse with Javascript enabled -- you are allowing websites to run essentially arbitrary code on your computer.
Wow, really? That's pretty scary. I guess no one has ever thought about the implications of that, or considered putting it in a sandbox so it can't do anything it wants to your computer. I think a strongly worded letter to the browser makers is in order!
