Leo and I catch up with the week's major security events. We then examine the ecosystem of web page advertising by comparing it to other "opportunistic advertising" such as that appearing on public transportation, highway billboards, broadcast television commercials and other public venues - which consumers have no obligation to consume. I eschew the implication that visitors to a web page have an obligation to retrieve third-party content, over which the website has little or no control, which consumes bandwidth, reduces online privacy, hinders performance, and potentially exposes visitors to malicious exploitation. And I believe this remains true even when a visitor's retrieval of such despicable third-party content would generate much-needed revenue for the visited site. Finally, I review the many operational features of uBlock Origin, my chosen HTML firewall, which effectively returns control to web users.
