Not going to happen. You don't understand the forces at play when biomedical researchers (I'm one too) do the work. A major reason more specific to this type of researcher that he/she wants to hold back the data is in the event it can be re-purposed for later goals. It's capital. The time and money spent acquiring the types of negative data the article talks about (mouse experiments) take big dollars. I'm not going to throw it away in an archive. It's like donating to a Goodwill bin some really expensive clothes you saved your money to buy only to realize after you bought it that it's the wrong size. You're totally going to try to make it work often for years before you give up on it.

If you take issue with my comment and have ever worked for a startup that didn't pan out (should be many of us here on HN), think of the scenario if someone told you, "hey, why don't you just be a good person and open source your app and give all your customers to XYZ?" (Setting aside the armchair quarterback guilt imposed on you) There are a few who do that, but if you've spent any length of time on your business, you're going to think of ways to re-purpose the investment you made it in other ways before you just go dumping it in an archive like Github or whatever.
