What the company isn't doing is billing you for the time they spend doing it, or having you spend your free time doing it while you are at home.
What someone does in their own free time with their own resources is their business. What they do while they are at work, getting paid is "company" business and should be treated as such.
Beyond this, I find it ridiculous that you're comparing humans with thoughts and feelings and limited time on this earth to wholly inanimate corporations. We should err on the side of giving humans more freedom and liberty.
That's exactly what Apple this case is about, an employee who is being accused of using his employer's time, money, and resources to not just search for a better job, but to create a multi-million dollar company.
What basis remains upon which they can claim that I used "their" time and/or their resources and/or their equipment to conduct personal business?
It's unethical, arguably, but most companies show again and again that they're willing to behave unethically toward their employees, so I'm not sure why I should feel bad for them given that employment is a two-way business relationship. The pervasive focus on employees being "bad employees" and simultaneous tacit acceptance of corporate dickishness is an insidious and toxic double standard that should not be tolerated.
