From the above poster:

I'm not convinced that there is a way that google maps could be as big as it is without ad revenue. Most people just wouldn't pay and the only reason that you would consider paying now is because the infrastructure that ad money has paid for has made it worthwhile.

Free community and paid, privacy-respecting efforts get squashed by the very presence of the spy-vertisers in the market, usually in the idea phase. A world without those products wouldn't fail to have equivalents for most or all of them, and likely quite a few actually free ones (though probably a little less convenient).

[EDIT] I'd add that sensible governments might well consider something like mapping/route-finding to be basic infrastructure and worthy of funding, absent free commercial options. Especially now that we've seen what that's like. So the US might be screwed but much of Europe and Asia could well come out with tax-funded alternatives to nearly-universally-valuable but expensive/extensive services like that.
