Re: Well that took long enough.
Ah the "nothing to hide so nothing to fear" crowd rears its naive head again. You do realize this isn't an all or nothing deal, right? You don't have to choose between giving up all privacy, or maintaining perfect privacy. There is plenty of room in the middle ground.
If Google didn't collect tons of personal information on you, they could still show ads that have to do with what you are searching for. If I search on "4k hdr tv" having a few sponsored links from Amazon, LG and Samsung to where you can buy or learn more information about their 4K TVs might be what I need. Certainly that's more likely to be useful in the moment than showing me a sponsored link for a place selling TItleist golf balls, based on an all knowing Google knowing I play golf and all my online purchases of golf balls have been Titleist.
The problem is they want to sell ads all over the internet, and want ads for 4K TVs and golf balls to follow me across the internet whether I'm reading news about GDPR fines or looking up information on wifi 6. And it may help make their mostly useless assistant technology slightly less useless. For those who are filled with horror that Google's assistant might end up dumbed down to Siri's level if they only knew as much about you as Apple does, you can always volunteer to shed your privacy if a moment's convenience is worth more to you.
Just give people the choice, you "nothing to hide" people can give Google full access to your medical history for all I care, and have ads advertising a discount lobotomy follow you across the internet.
