This is the best comment on this topic I've read to date.
I agree with everything you say and I still do business with Google. Let me go through your list.
1. No. Not me.
2. I hope I'm not that naive. I've made similar arguments to other people in related discussions.
3. Yep. I understand this.
4. Also true.
So - I understand those things and agree with you and I still do business with Google et al.
The thing is I also drink, fail to exercise, drive a petroleum-consuming vehicle and recycle poorly.
I do many other things that harm myself directly or perpetuate or accelerate trends in society I perceive as negative.
You might consider this apathy and that is probably true to some degree.
But I am also running a continual cost/benefit calculation on every action I perform.
Some of my conclusions are out of whack and some are frankly irrational but the list of things I consider every moment of every day is extremely long and I've decided that the cost vs benefit of doing business with Google is in my favour. I've evaluated the costs you set out above and decided they fall far enough down my list that I'll tackle them at some point after I've started jogging and voting, stopped drinking scotch and begun regularly volunteering at my local worthy cause.
