Yes because they know at the back of their heads, competing with hotels for a good experience is hard and they can't handle it. No airbnb is a four seasons. However they can compete in weird exotic places like a potato or a loft. It's basically Ringling Brothers circus as a temporary accommodation.
walking by recently, it appeared to me that the Four Seasons in downtown San Francisco has been converted to some kind of time-share ownership model. too much demand? insider club ? no idea
edit not the Four Seasons with a door on Market Street, the sign I saw was closer to the Moscone Center..
