I think the implicit assumption is that you are doing the majority of the development, and you want to make money from licensing, and you want to be the only one making money from your product. So basically, the plan is to make money exactly like a proprietary software company would make money, except that you make the product open source for marketing. I never understood why people thought that was a good idea. People like Open Source because they don't want to depend on a single vendor, and yet these companies want to be the only vendor of their Open Source solution. It doesn't make sense.
