This is highly dependent on the nature of the platform.
Data philanthropy was what UN Global Pulse came up with as a foundation for private entities donating data for public services. But now Uber has come up with another story. The site, which Uber will invite planning agencies and researchers to visit in the coming weeks, will allow outsiders to study traffic patterns and speeds across cities using data collected by tens of thousands of Uber vehicles. Users can use Movement to compare average trip times across certain points in cities and see what effect something like a baseball game might have on traffic patterns. Eventually, the company plans to make Movement available to the general public.
I recall telling the story of the US court that required a man with a light (and maybe a bell) to walk ahead of new-fangled motor cars to Sri Lanka’s Solicitor General. Was it apocryphal or true? But it worked. I prevented him from giving me a ruling that would have basically killed satellite-based personal telephony. So often, the vested interests (ah, an old word, going into desuetude) try to force fit new things into old boxes in order to kill them.
