I wrote this sentiment earlier[1], but I'll repeat it here.
If a dev wants money for his work, he should license his work as appropriate and demand payments. If a dev releases his work free-as-in-libre and/or free-as-in-beer, they don't get to complain if the donations are "insufficient".
Or to put it another: Of course a company won't pay up if they don't have to.
This guy seems to be considering making his work into a commercial product, so at least he has the correct idea. Speaking objectively I hope it works out for him.
