The difference lies in understanding how knowledge from research needs to be built from many stepping stones allowing you to infer something with certainty. If you're not used to that thinking people do expect you to close the loop in a very different way than what you set out to do (and which was the correct thing to do).

Someone else could, if they want to, build upon your work since they now know what results they can with good measure expect to get. Before your paper it was perhaps expected, but not to a degree where no one could've said with certainty that the results would turn out exactly the way they did.

For those who like their things a little more concrete:

Before this paper I knew a lot of people who didn't hesitate at all posting one of their public keys for everyone to see (donations, usually)

After, some of them consider it to be unnecessary leakage of information.

Great work.
