The pressure to publish is so high, promotions et cetera all rely on it. Putting together large datasets can be can be costly and time consuming and the hope is often to get a few publications out of it. I think citations need to acknowledge datasets more, as do promotions otherwise people will have large incentives to "silo" vertically and not share. A big issue that has no excuse is public access to journals though. It's amazing that the public pays for the research and then pays for it again and again in every library's subscription to the vampire publishing houses who do nothing other than distribute a few hardcopies that nobody reads and then gatekeep the pdfs (the editing and review is all done by academics, so it's just copy and typesetting that's commanding this huge price). Maths, physics and comp sci are some of the better disciplines (masters of LaTeX) for making things available online, but everywhere else it's horrible.
