This will do nothing to stop Google Chrome's market share tbh.

Installing an ad blocker is like the easiest thing in the world to do. Literally takes less time than watching the ad yet even most young people don't use it. It's the reason why Edge has such a high market share despite not being all that great. It's the default for many people so inertia will carry it forward. Google Chrome could literally record your screen at all times and sell it to the highest bidder and it would still dominate the market.
