I know, that's how it SHOUOLD be done..
I have a couple of Synchro's old CDs myself. He sent them to me as gratitude over something I helped him with, can't remember for sure since this was eons ago! Fact is, back then, he wouldn't take these donations. But now what happened mate? If you want donations for all teh frontend work, just release the frontend and put links to all that people need to download to omake the pack complete. You can also make an installer with all those files. Then you release that and make it donationware!
I wish also for AmigaSYS and anyone else who is taking donations for building setups to adopt the same approach. If you are accepting donations, you are breaking some of the licenses of distribution, and that's sad
