We may not like fees and the Boston promo may be tasteless but they aren't unethical.

I don't see a problem with surge pricing. If people aren't willing to pay then it won't last long. I'd like to see them have a bidding system to make it purely market driven.

I also don't see anything unethical with fighting unethical laws. Here in Austin we're in a very similar situation. The existing transportation companies have passed laws to entrench their positions and eliminate competition (eg min "black car" fares). Those laws are unethical. They do not protect us, they are anti-consumer.
