If you don't like that (like I do), you can also manually add it under Site Search using
AMA.
Once they hit the tipping point of broad cultural absorbtion (think Banksy) AND/OR raking in absurd amounts of cash, move their IP into the public domain more aggressively (think Disney, NYT, etc.). How exactly this would work should be debated.
They'd still own the IP and have all the rights to use it commercially, but other's would be able to use it as inspiration, remix and maybe even resell it if attributed (or cheaply licensed).
In other words: "IP-Tax" the unproportionally successful.
The point I was trying to make was that occupying mindspace, providing inspiration, being culturally influencal etc. are idealistic, non-monitary rewards that should be part of the equation when discussing alleged IP-theft, remixing, attribution and so on.
I'm not saying their shouldn't be any rules. All I'm saying is that there should be a discussion of how we want to handle these things going forward. This train ain't stopping.
Maybe your avg DeviantArt painter needs more IP-protection and -rights than Damien Hurst? Maybe an unknown, independent blogger doing important original research should be attributed more prominently than an article by The Times? Idk.
