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.
They do still have to cater to desktop users, so I imagine accessible websites for those platforms will exist for many years to come.
This is also yet another reason why it’s important to defend desktops in the face of people who think phones and tablets are “good enough.”
