It appears there is a lack of short-stay housing supply. AirBnB facilitates that market. Short-stay property owners should seek to spread their operating costs across multiple properties. This will drive out mom-and-pop operations - that is good business. The added wealth from leaner short-stay operations should make up for the temporary displacement.
The displacement is a process our political process has to manage. But spitting on markets for eroding the incumbent's edge is an old game for tired societies.
AirBnB undercuts existing hotels by sidestepping required regulations. There isn't a lack of short-stay supply; AirBnB just works more cheaply because it has fewer expenses.

The point of the parent comment is that that wealth is not kept in the town, but siphoned off somewhere else.
I agree with the other comments in this thread, AirBnB essentially opening up the market of desireable destinations to real-estate speculators, regardless of any impact this may have on the local population. Facilitate residential hotels, let speculators invest in them and handle the management, take a nice cut, damn the local regulations (and taxes) by claiming to be only an intermediary, and who cares about disruptions to the lives of the locals (directly through residential zoning violations, indirectly by warping the local real-estate market).
I think voters in destination cities and towns need to pass AirBnB legislation to limit residential subletting to something like 40 nights per year and collect sales and hotel tax on every transaction.
The picture of an appartment turned into commercial space (startup office) is telling of their "culture." Culture of cheating and disrespect, essentially.
Further, Culture is the achievement of various people pre-globalization. By discarding that, we are not becoming better, the results are positive in short term, but wait till it takes the nosedive, just like the real estate crisis of 2007-08.
Note: The existence of a minority of people gaming the system does not equate to what you claimed.

The $billion$ numbers don't make me think it is anything otherwise. Compare with the 'Youth Hostel' movement of a foregone age and how that broke even as a charity (no tax), with well meaning folk leaving property to them (no debt) and the 'youths' doing their own cleaning with bedding they brought. AirBnb stinks of speculative bubble money and it is only a matter of time before the rentseekers of the buy-to-let market get their fat arses into it.
What happens in small tourist towns when all of the available property gets bought by outsiders wanting to 'Airbnb'?
Let's face it, 'Airbnb' isn't about letting out the spare room or the flat whilst one is away for some pocket money (whilst helping some weary traveller out). Airbnb is about buying places specifically for rental.
So, what happens?
The few real 'Bed and Breakfast' hotels have a hard time of it and local people (not on big city wages or the money for a deposit) get pushed even further down the housing ladder.
So, even if the culture is not messed up in the hip Mac-book Air stuffed office of AirBnb, the culture could be messed up in some far off town.
