Not sure it's that simple. A slow release can make the whole thing better known. Just look at Julian Assange and Edward Snowden. Assange dumped everything he had at once. It was in the news for a bit (including that some of the stuff he put in there had the potential for putting people's lives at risk), then it was out of the headlines. Snowden, on the other hand, worked with journalists to release things bit by bit, focusing on the important documents and spacing out the releases. Result: it stayed in the news a lot, lot longer than the things Assange released, and as a result people on average know a lot better about what he revealed.

So if anything, this is helping more people know about it. Think about it, the files were supposed to all be released last year. It's still in the news, because of all this.
