Google is deliberately doing this to break ad blocking for Google ads while still allowing ad blockers to work for non Google ads. Most users probably won’t care enough to change browsers or many won’t really notice
If so, they are doing a crap job of it because uBlock Origin Lite successfully blocks all of the search ads on google.com
That's the best way to get antitrust breathing down your neck.
So, with talks of Google monopoly ramping up, either this is extremely shortsighted and reckless, or they will choose to not throw oil on the fire and will not go down that road.
I don't know much at all about the ads ecosystem so I have no idea how may adsense should be playing in either trial though.
