Science and business

Although I work in the software industry, I am an academic at heart, so I keep abreast of what's going on in the world of research. I'm also interested in the cozy relationship that academic institutions and businesses are being encouraged to undertake here in Canada.

A recent article in The Economist describes some of the problem with positive results oriented science, and notes

On data, Christine Laine, the editor of the Annals of Internal Medicine, told the peer-review congress in Chicago that five years ago about 60% of researchers said they would share their raw data if asked; now just 45% do.

I wonder, if I'm a researcher being funded by a company (perhaps being viewed as labour with good tax benefits), would I be willing (or even allowed?) to share data that may be generating revenue for said company?

I have my doubts.
