I don't know if this was made to preserve bandwidth, but if you're that worried about data usage, you're not gonna be loading up animated gifs. After watching a full gif, they do tend to take a wild turn from what you expected, as Nick mentioned.
Seeing the full preview would be nice, as is the norm for literally every other messenger on the planet.
