Edit: Jesus Christ, people. If you buy a $150 Thinkpad made by slave labor instead of a $1,200 MacBook made by slave labor, you're still supporting a capitalist economy based on slave labor. We all do. We have no choice. The number of smug liberals in the comments saying "well I buy a cheap used laptop" or "well I buy coffee beans and make my own coffee" are completely missing the fucking point.
Don't tell yourself your consumption is moral. All of us make unethical choices every day because there is no ethical consumption under capitalism. Accept your shame and guilt and let it drive you to do better.
Oh, I didn't know you needed apple products, the most monopolistic tech company to exist, to survive. That explains why their fans are so rabbid. I better switch from Linux otherwise I'll die.
It's not all that uncommon for workplaces to require a specific OS
That's a good point
Monopolistic means there are no other options. That's the definition of monopoly. She needs apple products because they're a monopoly. The refutal is in the words you used.
