Original title is about "Google cracks down on VPN based adblockers". Changing "VPN Adblockers" to "Android Adblockers" is misleading, at least.
BTW, I'm using Brave because of having u-block origin, and I recommend it. Needed to change the default chrome widget for a brave widget, and lost the chrome sync. Other than that, works as a charm.
