Sorry I just saw your thread.
I think it’s unnecessary to automatically reward artist in the same way that taxes are unnecessary. Developers could crowdfund their apps or find other creative ways to fund it before or while it is being made. Apps can receive voluntary donations after they are made but I don’t think they should depend on them.
For apps I don’t think it’s so bad because most apps would be open source and you can just fork an app and improve it and put your own wallet address.
But personally I would prefer not to put any wallet address because I don’t think it makes sense.
I am also very concern about an automatic rewarding for artists.
I’ve started a new group called “The End of Intellectual Property” and a thread on MaidSafe if you want to discuss this further.
