Kettle, Pot, Black: yes
Sounds to me like both MS and Apple are guilty of a design philosophy that has tiresomely demonstrated, over and over, its capacity to fubar almost any machine. To wit, doing the user favors he didn't ask for. We might call this the "oh you poor dear, here, let me give you a hand" philosophy. An everyday example is the Boy Scout who forcibly drags an old lady across the street when all she was doing was checking out the shirtless dudes on the construction site there.
Don't auto-download anything unless the browser is going to render it.
Don't execute anything without the user explicitly asking for execution.
Don't install software on the sly. [This one is mere sneakiness, not a bumptious attempt to make your machine "user friendly."]
Don't design your systems for the clueless. The clueless are cluelesser than you can possibly imagine, so the only viable strategy is to assume a reasonable level of intelligence. [See footnote]
Don't, ever, *guess* anything. When you guess, no matter how clever you are, you *will* guess wrong a considerable amount of the time.
Don't, ever, try to guess what the user meant when he input wrong data. If it's wrong, it's wrong, just beep and say "error", and if Joe & Josephine Drooler-Sixpack don't understand, well, tough. As regards the internet in particular, it wasn't designed for idiots, it's not idiot proof, and don't try to fake idiot-proofness.
I leave it as a class exercise to determine which company, Apple or MS, is more often guilty of this class of design error.
I remember the good old days of Windows 3.1, that (iirc) didn't do you any favors at all. Ubuntu Linux also seems to be free of this mistaken idea.
IT? icon because it's simply good manners to refrain from imposing unasked-for favors on others, not just an IT issue. They don't appreciate it, and doing so implies you think you know someone else's business (or how they want to lead their life) better than they do—an extremely patronizing attitude. Miss Manners (tm) will back me up on this.
Footnote: since half the population has an IQ 100 or below, by definition, where does that leave us?
