Think about it, Google Maps is (I think) the biggest collection of map data and information on locations everywhere around the world, yet I don’t want an advertising company knowing that I just went to a fast food place.
YouTube is an endless trove of video content that anyone can contribute to, yet I’d much rather not give an advertiser information on every little interest that I have in video.
It’s so bad for you, but it’s so good.
I am not even logged in. I clear my entire browser every day and youtube still tries to shove propaganda. I use Firefox + uBlock Origin on Android. Seems like if you dont use an account, they just show what the average person watches, which is apparantly right wing shit.
