wow... your comment indicates that you have never read any of his stories, and is singularly uninformed.
He is alternatively described as an expert swordsman, boxer, and master of disguises. More of his mysteries were solved through observation than by main force, but, nevertheless, an action adventure Holmes would be in keeping with the original cannon, and a much more exciting movie than one without.
Bzzt. wrong. try again.
You confuse "owner" in this case with "user".
The owner of the machine is the business that owns it, while the user is the poor guy sitting at the keyboard. It is perfectly reasonable for the owner to want to protect against a rogue user. But all of the comments in the grandparent thread still apply. The legitimate owner (even if it is a business) still owns the physical hardware and has all the same concerns a regular person would have.
If all else fails, lower your standards.
