Also, when pi-hole and mitmproxy are our only options to know what our device is doing and to block things we don't want, then we've lost. The web browser is basically the last bastion of control that we have with its devbar and networkbar and all. Blocking content/requests is something our devices should be able to do themselves.
It's a miracle of history that we have the browser, and it's hard to imagine us having it had it been invented today. We need to fight to keep it, not dismiss it with "ugh web tech amirite?" while we regress to native app black boxes as our only option.
