The issue w/ Uber and Lyft is one of employment laws rather than regulated trust networks. If we changed the laws/prosecuted the companies they would have to raise prices due to higher employee wages/compensation which would have the ultimate effect of weakening the network as people looked at taxis and public transport as viable alternatives.
So ultimately my point is that we should look at how attractive the service and why. In the case of Uber its because they are able to exploit an oversupply of low skill labor to bring prices down. This combined w/ advertising and promotions has created a strong network. Not sure it's the govs job to step in and weaken/nationalize that network. Perhaps regulate the employee/employer relationship, but this is nothing new.
OT, but this is why news anchors have to say "the obesity rate in the US has risen to its highest level ever, scientists reported today."
It doesn't work quite as well to use a different, say, social media platform, when all my friends are on Facebook.
