That's a lot of businesses. The local liquor store "injects themselves" between you and Budweiser when they sell you beer. It's not inherently evil or unethical to act as a middleman, especially when you provide additional value that the original business does not.

Yes, the unethical part is stealing the Google search results, taking the tips from the drivers instead of distributing them, etc. All the stuff you heard about over the past years. If they had an ethical business, we wouldn't be reading this article.
