Yes, but until such time that is happening, you are also an asshole for not tipping where people are being paid under minimum wage.
Amazingly, both of these concepts can be true simultaneously!
You not tipping the service worker will never have any impact on the company's decision to be assholes and pay less than minimum wage.
Working with local politicians and boycotting said companies might. But most people in the US complaining about this shit want to have their cake and eat it too.
