Not hard to guess.
To those who already know what happened, it provides information about US surveillance capabilities in the area - release undesirable.
To the ordinary Russians, and to those elsewhere who do not believe the US, it will be US propaganda, fabricated, will not be believed - hence release is of no benefit.
To those in the west who believe US statements it will be redundant because Obama already gave the answers - hence release is of no benefit.
