wrong.

Crowdsource is significantly different from open source.

Open source is Linux winning because you don't need to pay Microsoft, anyone can fork, Oracle/IBM and Microsoft's enemies putting developers to make it better and so on. Today .NET runs on Linux.

Crowdsource is the usual bs that either through incentives (like crypto) or by heart, people will contribute to free stuff. It doesn't have the openness, liberty or economic incentives open source has.

And Google has lots of crowdsourced data on Maps, I know lots of people who loves to be a guide there.
