> Is your ISP actually doing that to you right now? Or is that just hypothetical? I was on a Southwest flight earlier this week which did exactly this, using HTTP injection to display an overlay on every HTTP page. It's certainly useful to provide flight information (or Amber alerts, weather information, billing alerts), but it's Just Wrong™ to violate the integrity of a communication to do so. Perhaps there should be some standard protocol for ISPs to send messages to clients, permitting the connected OS to determine how to display them?
