For me, it's more about the companies than the product (which, like I said, is probably an unsatisfactory criteria for most people).
Glad you're enjoying Google's services though :)
I think we just have different worldviews. Certainly economics are important, but I try not to boil everything down to dollars and cents.
And for sure, Google has done a ton of useful and interesting things that I'm grateful for. But they also contribute to undermining online privacy, and use their size to wield disproportionate power in politics, etc. etc.

I agree that Google contributes to undermining online privacy, but I still don't see Dropbox doing more in that regard. I'm sorry, but I really am not a fan of Dropbox after my experience with them, so I am inclined to be a vocal critic of their service (or lack thereof).
