The point is not to centrally agregate data in the first place because the synergetic effect is too big.

Knowing 24/7 where you are is one thing, and knowing everything you search is another, but if you combine these two, it already becomes very scary.

Google knows so much more. It is a wet dream of spying agencies.

What can we do about it? I think most people don't understand technology enough to see what happens, so education might be the first step.

I personally avoid Google.

Data on Mozilla's servers can't be cross-referenced to add to the profiles of visitors and track them across the internet.

If everyone on the internet created their own analytics stack, the data integration issues alone would prevent aggregation and abuse in 40 years time.
