As much as I loathe ads myself, I don't think it's a good idea to default to blocking ads, not the least because the definition of an ad is a little hard to capture completely without either false negatives or positives. Different people also have different ideas on what they consider acceptable ads, so it could be a form of unwanted censorship to some.

Default to showing all the content, but let people make their own choice on what to filter out.
