I don't buy it.

The "weird stuff" is always distant, blurry, shot under terrible conditions, etc. Yet when a research team, or random passer-by snaps a photo of some never-before-seen, or thought-extinct creature, there's no difficulty in getting a quality image, either on the initial sighting or shortly afterward. It's only the "aliens" that are so problematic.

As for the idea that "they" are doing it deliberately (and perfectly)... it reminds me of the TIGHAR folks and Amelia Earhart. TIGHAR knows that Earhart crash-landed on Nikumaroro (Gardner Island), so every piece of information they see is interpreted through the lens of how it fits with that interpretation. But they have no root basis for the conclusion, just that they really want to believe it.

When faced with the question, "Why are pictures of possibly alien UFOs blurry?" two (of many) possible answers are "because if they're not low-quality we can tell they're not aliens" and "because the aliens are carefully arranging circumstances so that pictures of them are always low-quality" I know which one I'm putting my money on.
