Doesn't that make sense from a defense standpoint? If my house was under seige from a gang like let's say, the police.

And my kids started posting pictures and videos from the inside of the house showing that I am not watching the back windows. Doesn't that make attack very trivial?

People even unwittingly can post a vulnerability that americans and isrealis would immediately jump on.

It's not really a difficult calculation to make. Whether that is a good or bad system depends on other centralization factors more so than comms channels.
