It's interesting, while I don't live in one of those cities, I've been meaning to drop Uber over all of their apparent complete lack of ethics. I hadn't done so yet, but this article has reminded me of it and I'm installing Lyft now.
As much as we hate to think it, both awareness and social proof in decision making matter. And while I wouldn't have admitted it, part of it was thinking in the back of my head that quitting wouldn't make a difference. Seeing the graph showing the real impact of the #quituber campaign was both surprising and to be perfectly honest a bit motivating to me to keep to my word to use Lyft. Maybe not a full quit, but at least a 50/50.
