I really don't understand the problem with Google analytics. Anyone who is able to explain that in easy terms?

So they are collecting data about me to show me better ads. Isn't that what I want? They compare my data to a collection ("look-a-likes") of others that match my data fingerprint. What's wrong with that?

The way I understand it nobody is interested in me as a person (which is a bit sad, but that's a different story...).
