The food you order online was not stolen from the server/bartender without their permission or compensation. Even if the analogy holds, this is whataboutism, and in the U.S. at least tipping is a fucked system too.
If you stop going into the restaurant they stop scheduling servers. You or the restaurant didn't get permission from the server who isn't working there anymore.
It's about applying your outrage evenly. Why put artists over a servers? Why do you drive when not using horses means many blacksmiths positions disappear. Technology that is accepted by society changes society. Artists will continue to evolve and create messages about those changes. No need to worry about their plight. Worry about translators or other industries that can't easily provide the same value. Artists are the one group who will survive and thrive.
