The scary thing about this is that, while you may have a good "security hygiene" around your devices, you have no control over others who you socialize with.

It's a bit like ending on Facebook even though you have no account: someone posted a picture of you, you got tagged, and now you exist in FB.

All it takes is one person with an infected phone to show up around a table of a private event/conversation and, through no fault of your own, you get recorded.

The moral of the story (that I've been trying to follow for a few years now, quite unsuccessfully I must add), is that if you want a private conversation with someone (or a group of people), you need to keep all devices away.

On the bright side, it has taught me to be very diplomatic in my discussions with others. My default behavior (when I don't slip) is to assume that whatever I say could become public somehow.
