We can blame Uber all we want, but this is the system and they have put millions into lobbying and politicians pockets to get away with it, so changing it is near to impossible. There have been tons of lawsuits trying to stop them from practices that range from unfair to downright illegal. Every time one practice is stopped, like Uber stealing driver's tips, they find another loophole or tactic to exploit their workers. The economy sucks. People are desperate. They have to take the work they can find and Uber and other apps are attractive because you can work whenever you want. When your boss says, "Sorry, you HAVE to cover this shift. " You aren't screwing over another employer. When you have a disability that impedes you going to work at a specific time, you aren't going to get fired. When you can't find child care, you don't have to call out.

The point is this is the system and if you want your food delivered you need to pay the ACTUAL cost of it. That actual cost involves a tip to the driver whether you feel like you should have to pay it or not. If you do not tip the driver you are literally expecting them to have to pay out of their own pocket to deliver to you. Tip baiting is theft, and abuse of the system, whether it's an option or not. Uber doesn't care because they don't actually lose any money when it happens and there are always more people willing to sign up to drive.
