When does the co-authorship line end for a PI's data
The German research foundation (DFG) has some guidelines on authorship for research publications (including an English translation towards the end) which put specific criteria for being named as an author. Among others, it says that those "who have made significant contributions to the conception of studies or experiments" should be listed as authors. 

In my understanding, getting funding for a project requires describing the conception of the data collection in quite some detail, so anybody who contributed to that part of the proposal should be included as an author of the resulting publication. Importantly, the criterium is not having brought in the money, but having contributed (significantly) to the conception of the study.

The only exception to that rule would be if the paper under discussion does not "publish" the data, but "uses" it in some other way and can include a citation to the original publication of the data.
