I've never understood why tipping, specifically when it is completely optional, threatens people or turns them off. If you don't tip a Lyft driver, they aren't going to give you a dirty look or treat you any differently, especially since you get to rate them on their service. You can complain that people should be paid a fair wage, but they aren't. I wish for many things, such as the end of warfare, but I accept the current reality that I live in and that I don't care enough about tipping to dedicate time and energy to affect its change. I'm not going to go out of my way to change some business's wage policy. It's sub-optimal, but what isn't? Humans are terrible at setting the correct prices for goods and services. The market does not provide either for a number of reasons (eg we don't take externalities into account, love to socialize losses and privatize gains without getting caught, etc.) It's been this way for longer than I've been alive and has shown no signs of abating. If it bothers you that there is an OPTION to tip in an app, there's some insecurity there for a reason. Honestly, I like the system. I tip well at bars. As a result, bartenders will occasionally give me free drinks, engage in meaningful conversations, or just really go out of their way for me.
