Not asking for tech support here, just wondering if in theory it would be possible to create a plug-in or even a complete browser that blocks ads in a way that’s impossible to detect. One model that comes to mind is a quarantined / containerized non-blocking virtual browser which queries the web server directly, then the UX filters the content from that container and presents it to the user ad-free. As far as the web server can tell, the containerized browser is just vanilla Chromium.
I have definitely noticed an increase in embedded ads. I listen to a lot of podcasts and the “cool” thing with those is to detect where you are downloading from and inject local/targeted ads into the ad breaks. Fortunately the 30-second skip button still works.
