When you see httpS: that S tells you all transmissions are encrypted. They can intercept your transmitted data, but it is extremely difficult to decipher encrypted data.
I didn’t explain that right apparently. I am fully aware of how sockets work, “content” is not the curiosity. I was talking about stealing data bandwidth from WiFi connections of folks who do not have these devices or part of the network. This would put an warranted load and burden on others without permission. It would be forced “cost sharing”.
