On the one hand, ad personalization is kind of creepy. Like when you start talking to your mom about a vacation to Bora Bora and then you see a Facebook Ad for it 5 hours later . . .you’re like “WTF?!”
Sometimes that stuff is coincidence. Other times – it seems like spying. Regardless, is it a GOOD thing? Well, we did want to go to Bora Bora, so the ads were much, much more useful.
Personally, I prefer to have ads targeted for my tastes. I don’t want to watch ads about feminine hygiene products. If I have a cat, I don’t want to see ads about dogs.
If you read Edward’s Snowden’s book, you realize that there is no such thing as privacy. The Government can pretty much hack into every device it wants to and spy on you all day long with no oversite. Google knows more about you than your siblings.
So Ad Personalization? I leave it on. Seems to me the benefits are worth it.
