You CAN install OS X from a USB but I am not sure if it would bypass that restriction. When I restored my 2013 Mac, I had to install OS X Lion and keep updating it from there, but they may have fixed that issue
I use it on iOS with uYou+ and I haven’t seen it, I also used Video Lite’s Adblock as well as on Safari with normal ublock and haven’t seen it either. Maybe it’s not on mobile yet
But don’t they increase the price every year
