The question we really need to be asking is, "Why is there now a two-tier service fee system, under which Airbnb's total take from the bookings of regular hosts is up to a whopping 25% (mandatory Shared Host/Guest fee), while since June 4th, professional and commercial operators on the platform have the option of the Host Only fee, with Airbnb's total take on those bookings being just 14%?
Whether it's called guest fees, host fees, shared fees or just plain old booking fees... no matter what way you slice and dice it, the end result remains the same - Airbnb creams off up to 11% more from the bookings of regular hosts, than it does from the bookings of Pro "hosts". Some would see that as Airbnb gifting yet another unfair competitive and pricing advantage to the pros, making it harder and harder for small hosts to fight for their lives on the horribly (and in many jurisdictions, unlawfully) unlevel playing field that we're wrongly being forced to compete on.
Only a matter of time until the Pro listings have "No Service Fees to Guests!!" emblazoned all over them, obviously making them a much more attractive propostion for searching guests than the offerings of regular hosts, with their sky-high charges for guests. (And still, in clear breach of EU rulings that should have been complied with a full 7 months ago, Airbnb continues to force small hosts to battle for survival in the same searches as huge corporate players with their preferential tools and policies, thousands of listings and hundreds of millions in venture capitalist and investor funding behind them. But we don't seem to have much of a problem with that grossly inequitable, discriminatory, anti-competitive treatment at all - or if we do, we certainly aren't voicing our objections to it very loudly)
Just the latest nail being hammered into the coffin of small, independent hosts by Airbnb itself. And we've all been way too distracted by the likes of the never-ending review/ratings/SH insanity, to even recognise our impending - and carefully orchestrated - demise creeping up on us.
