All open source projects start somewhere :) Besides, open source is the way to go and it doesn't make sense for any company to own it for the below reasons: 1. No bidder wants their code hosted by some 3rd party hidden away from them. 2. No bidder wants their code hosted by especially another bidder. This introduces huge conflict of interests and defeats the purpose of header bidding. 3. All websites can benefit from this open source project and make each others' implementation better. 4. So far websites are SCREWED by some bidders that make blocking calls. Prebid.js ensures all calls are async.

The beauty of the project is to host a true, fair, open auction in the browser. Open source is the way to go.
