I don't get the hate, I think it's a great idea. It's completely opt-in and both sides win.
I consider advertising to be offensive, and think it's appropriate for a society (big or small) to control what forms of ads are allowed via law. I'd like to see limits on what sorts of trade-offs we can make with respect to ads, so that the life experience of a citizen need not be drowning in advertisement.
Riding a taxi in NYC (where ads are built-in to the cabs and cannot be stopped) is a distinctly unpleasant experience compared to elsewhere. We can only have so many forms of transit available to the people of NYC. I would rather we choose to remove the ads and pay for the transportation system via direct-monetary transfer, or taxation, or some combination. shrug
Yes, they do. With some exceptions, gambling is an harmless activity that people engage in just for the fun, not expecting to win. Or quoting Motörhead: You win some, lose some, it's all the same to me / The pleasure is to play, it makes no difference what you say / I don't share your greed
