Google ramps up its campaign against ad blockers on Chrome.
I agree folks are overestimating how many will switch. but also maybe you're underestimating too - a lot of browser installations are managed by the "family tech guy". the father, mother, brother, sister, aunt or uncle who sets up everyone's new laptops on Christmas and has the suggestions when you look for a new phone. we all know the type. a lot of us are the type.
setting up granny's laptop? I'll install whatever browser lets me automatically block the most "1000th visitor!" banner ads and change the desktop icon to the old AOL icon because that's all she knows the internet as. she doesn't know of care about the browser options so it's up to me. Chrome used to be fast and simple so it was the right choice. Firefox has caught up a fair bit on UX simplicity and speed and now offers better blocking and general security, so it just stole the crown for these installations imo. I trust it more to not let her mess the computer up, so even if I'm not using it as my main personal browser, it gets use here.
