Monopoly behavior is not what you describe it to be.
Not providing customer support is a whole different issue and has nothing to do with Google maybe being a monopoly.
Monopoly behavior is buying out competition forcefully and dominating a market with an unfair advantage ensuring they are the only ones in the market. I personally don't believe Google is a monopoly in the Search Engine market but that's only my opinion.
That is the plan eventually, but airbnb charges 17% in fees, we hope to charge half that or less if investors ask us to eventually implement fee structure
