People keep finding hidden cameras in their Airbnbs

Airbnb has a scary problem on their hands: People keep finding hidden cameras in their rental homes.

Needless to say, this netted a social media post from me about the potential "cost: of staying at an unlicensed and uninspected "BnB." Heavy-handed I know, but this is war.

I get these cameras are hidden, and deliberately placed for voyeurism, and that's a travesty, but there are a of legitimate places that have installed cameras in every nook other than the actual guest rooms.
Common rooms, hallways, patios, swimming pools, etc.
Unless you were looking for them, you wouldn't know they were there. There's actually no expectation of privacy any longer in any public area.

Just some odd comments:
We are a wired world today, many people have cameras to check on their homes when they are away as part of their security system. Our son has cameras to check on the pets when he is away.
So, the whole theme of Airbnb is that I'm "sharing" someone's home, if I'm "sharing" your personal space then should I expect the same level of privacy that I might expect at a hotel or inn? Yes, I think they are running a big business, but I can't have it both ways, either it should be a business or take what I get.
If those guests who are "sharing" the home are plundering around the house looking for cameras or who know what else, maybe the home owner felt a camera was needed for security.

You should look up all the people complaining that porn is shot in their home. It's hilarious!

I've expected a complaint on this subject, but never happened. Our zoned heat pump system has auxiliary temperature sensors in several rooms apart from the main control which is obviously where I can get at it. When I first looked at the installation, little plastic square high on the wall overlooking the bed, I thought, this is going to be a problem. Maybe the label Honeywell satisfies the worry, or nobody looks up.

JimBoone and Morticia have pointed out a perspective that I hadn't considered. While a camera over a bed would obviously be voyeurism, can the same be said for ones in common areas? If you're in someone's home, should you expect full privacy? Also an excellent point that the Airbnb owners might want to have cameras to record evidence in case their rental gets damaged.
