Telescope is a bad analogy. This is more like the neighbor is inadvertently projecting a feed from inside their house onto a display outside by the sidewalk for any passers-by to see.

No.

This isn’t a passive “walked by the window” thing that you might have unwittingly viewed. To actively search for open cameras by crawling every IP then creating a tool to see them, then choosing to watch the footage is a very active, deliberate choice. No one is viewing this footage without making a multi-step choice to view it.

Everything is a bad analogy, because the internet has something like 6 billion of us on it these days.

We evolved for small tribes, e.g. Dunbar's number is ~150. Roughly 1/129 of the people on the internet are software developers, so in the days of everyone living in villages your in-group would include roughly one person who thinks like we think.

"Inadvertently live-streaming to the 1/129 of the world who consider searches like this to be trivial, with zero feedback unless you found your home accidentally went viral" is not like anything we otherwise experience.

If anything, projecting onto a nearby sidewalk as you describe is more like "I was bathing after my day's work scribing for the king and wouldn't you know it, that 𒈗𒍠𒄀𒋛 living by the temple decided to walk right in and say hi! Doesn't even think to knock, just opened my front door and walked right in.", while the closest thing you can find to accidental live webcams in old writing is gods spying on mortals for fun, making us the Anansi, the Loki, the Eshu. And for the furries, the Coyote.

No, it really isn't...

Not really? It’s just like not closing your blinds and being shocked that people on the street can see you.
