I don't see the problem here.
NFSFAN is releasing his Vogue ROM whether or not you donate to him. Many ROM authors/bootloader hackers/3rd party application developers seem to be asking for donations before major releases come out. I'm sure they've spent a long time testing/debugging/tinkering and if you enjoy what they do it may be nice to try and help compensate them for their time.
They're asking, not requiring.
It isn't as if he is CHARGING MONEY for the ROM itself. If he did, there would be many people pissed at him... including some copyright holders (i.e.: Microsoft).
There is nothing new to see here. Move along!
