> They want all the benefits of renting out their place (in most cases, it goes against the original intent of renting a spare room, or family home), but want to make the experience less than ideal for customers.

In the first part of that sentence you characterize the transaction as akin to renting out a spare room, but in the second part you characterize the guests as "customers." Historically, if you rented a room from someone, you were subject to all sorts of rules, invasions of privacy, etc. In many circumstances, that's still the case (e.g. with live-in nannies).

What's actually happening is that guests treat AirBnBs like hotel rooms, and hosts are doing the same thing. It's just a commercial, arm's-length transaction.
