So the question is then, are any of them going to be prosecuted for perjury and lying under oath? I believe you must swear under penalty of perjury to send a DMCA notice.
Probably not, thought they certainly deserve it. My guess is that the owner of LendInk has neither the time, nor the resources, to pursue all of the authors that filed false/ignorant DMCA notices, and more likely wants to wash his/her hands of the whole thing.
It's just one of those tragedies that will never see any kind of justice. Welcome to the world. It's another day.
They're not committing perjury. Perjury requires that someone know that what they are saying is factually incorrect at the time they are saying it.
The authors in this matter are not technologically sophisticated enough to understand how either the Kindle Lending or LendInk work(ed). They actually believe that it is promoting piracy. Thus, they are not committing perjury in their DMCA notices.
