This is the type of NIMBYism that is contributing to the housing policy problems. Instead of using nuance and recognizing the good and bad, only the bad is focused on and the proposals are to throw it all out.
Generally NIMBYism involves push-back on policies that increase housing density to help more (and generally poorer) people live somewhere. AirBNB without regulation (and enforcement) doesn't help more people live in an area - in fact it removes long term residences from the market in favor of generating more revenue for existing property owners. Reducing the long term housing supply increases demand and prices, thus keeping poorer folks out.
Personally I don't mind AirBNB if it's only people renting out rooms in their residences. For instance here in Portland the law requires this. But it's poorly enforced.
NIMBYism isn't only about housing, it refers to any pushback on a change that is generally agreed as good/useful/necessary on the basis that "sure we need this thing, but not where I live".
Currently we hear it a lot regarding housing density, but it's also a factor in locating sewage treatment plants, nuclear waste disposal sites, etc.
