My thoughts on it...

They're not paying you for the software on the phone... They can easily enough come here and do everything themselves. What they're paying you for is the time you spend setting up their phones, and customizing everything for them. Charge as much as you want for it, and keep the profits for yourself. They created the software of their own free will. You shouldn't have to pay them after the fact.

If you choose to donate some of the money to the authors, that's your choice, but don't feel pressured to do so.
