From what I gathered, Prema helped some guy with a bios mod, possibly an experimental non-public version, and the guy just posted a link to the mod on another forum, no credit, no Fs given. It's just sad. When you ask Prema for help, he literally goes 'donate whatever you think is appropriate, I'll help you anyway', on one, single condition that you won't share it.
Donation-ware is based on trust, and this trust was broken. If Prema goes commercial from now on, I'm only happy for him.
