"open source" and "business model" in the same sentence... next you're gonna tell me to eat pudding with a fork.
I think you should try eating pudding with a fork next

practically speaking, the only downside of using a fork (or chopsticks) is scraping the bottom when you are finishing up.
Depends if you are in UK or not.
