Do you support billionaires?
Are you on Facebook, Instagram, and Meta?
Buy things on Amazon?
Have an account with any Google service?
Use Microsoft Office, Windows, GitHub, or any of their other products?
Shop at Walmart?
These things all benefit billionares. Even if you don't directly pay them. Even if you use a fake name.
It's all of our individual actions that make them rich.
I'm not saying to abandon all these things, just be mindful of your choices.
