These kind of talks depress me somewhat. It shows that there is a need to educate scientists into sharing data. Which is kinda sad, because scientists should know this and share by default. It shows current state of science is not yet very far in sharing data with everyone.
The main blockers of open science will probably be paper publishers and commercially funded science. For publishers, it's easy to see why: their market will be reduced to only peer-reviewing services. For commercially funded research (especially political commercial science): It's in their interest not to share the data. Because sharing it would allow critics to scrutinize the data and filter out the ugly.
