It was unfortunate that they used that image during the presentation, but it must be noted also that it has nothing to do with the Nimitz video/incident itself. Some people may get confused now, just as some are about the two different videos.
That image really shouldn't have ended up to the presentation if they had done their homework. It should have been already obvious from the Fightersweep article they were referring to back then that no such image was taken, and it doesn't even look like a tic-tac. What's worse, they actually had Elizondo sitting there, the man who should have seen all the relevant data. He should have known and he should have been consulted before such presentation was made public. Similarly they lost their credibility right on the launch event by telling a "Mars attacks" type of version of the story, which was incompatible with all the credible sources. That shouldn't have happened either. But then again, they are an entertainment company, and that's what they made out of it.
Similarly it wasn't that surprising those videos got mixed up in the media. They were released at the same time, one being an interesting event with a dull video without audio, and one was a more interesting video with no context whatsoever. It's not really that surprising that the media picked and combined the interesting parts.
What's actually worse is that they just let that confusion continue for a couple of months, and it still does, with little effort to set the record straight. Because of that, they took another big hit on their credibility, and worse still, so did the Nimitz event.
What this subject matter really needs is credible, accurate, no-nonsense type of information that is shared as openly and promptly as possible. That's not what they have done so far.
