I know Google doesn't literally sell my personal information. They collect it and use it to match a demographic that advertisers want. But the fact remains that Google collects my personal information -- they couldn't match my demographic otherwise. And that means that Google itself is a giant repository of everyone's personal information, even if they choose (today) not to sell it, not to give it to governments on demand, and not to misuse it in any other way. But should we trust them forever not to do so? And why?

But that's what you said:

> "make shitloads of money selling everyone's personal information to advertisers."

It's a very important difference between trusting Google with the data, and trusting a random advertiser.
