I personally see the models completely different.

One is free redistribution, which is an open source project.

The other is a SaaS product, which is closed source. (Pro examples, priority queue, email support, etc)

You can build a SaaS around your OSS, but do not call it asking for money. You are more or less changing from a project to a product model. People happen to pay for perceived valued products more often than sponsoring projects.
