Alternative business models: open-source, crowd funding and tokenisation

At the Cambridge Product Management Network meet-up, Liam Crilly presented the fundamental business routes for open-source project. I talked about the various flavours of crowd-funding. 

From my experiences at Fetch.ai, I proposed that open source and crowd funding are prerequisite to tokenised business models. 

I left a question with the audience: If Tim Berners-Lee came to you with the idea of a web server + client browser, would you advise him to open-source or tokenise it?

What do you think?
