Unless you are using SSL based connections, there is no such thing as privacy on the internet. The sooner people come to grips with that, the better.
The possibility exists that someone could intercept communications, if that communications is not encrypted, even read the contents exists.
But that doesn't mean that those communications are "public", for all to see. And that's completely different than gathering data on all of our systems and posting it for all to see.
Again, even though the technology exists, it's still none of my business who's talking to your systems and none of anyone else's business who's talking to my systems.
