... should companies be nervous about this also though? Is the decision for their payroll info to be visible to unknown buyers an intentional, well-considered one? Is this effectively leaking potentially strategically important info?

Like, I haven't seen this happen, but could a recruiting team buy the compensation data on staff at a competing firm, identify those that look like a good deal, and poach them starting with a "we'll offer you k% more than your current employer"?

Could market analysts use this data to notice when a company starts firing more people, or starts giving fewer/smaller raises? What if the next time your company showed up in a Gartner or Forrester report, it came along with a caveat "however given decreased investment in staff, their pace of product development or quality of client services may be at risk."
