There is arms race and you want adblockers (good guys) to give up any improvements in perpetuity, that is a recipe for losing.
Me installing uBlock for parents has improved their browser experience and security. I'd rather risk uBlock being compromised and having to phone them to uninstall it than have them being at the mercy of adtech, spyware, and scammers companies in 5 years.
A personal computer has always been very complicated and using it has always been a risk in itself. I remember a time when a virus could damage the computer's hardware, and someone who knew how to program in BASIC (edit: or LOGO) was not considered as a "minority".
My point of view is that we need to make users aware of the risks and make them more responsible because things will not get any easier.
No need to optimize, I switched to Firefox, the browser for the minorities ;). I really liked Chrome though.
How has that been working for the last 30 years? Why would it start now?
Computers have been mainstream consumer appliances since the “multimedia PCs” were a thing in the mid 90s. Most people no more want to program computers than they want to fix their own cars.
