Yes, I thought of that line, that, perhaps, is the only thing that can be used here...
I think this episode is an interesting one for one more reason at least - it shows the difference between conspiracy theories and actual conspiracy. Notice, that there were conjectures, but those conjectures have been then strongly supported by evidence.
How woulkd the situation look if it was not a real conspiracy? Well, imagine everyone having these suspicions, but not being able to confirm them. They look at a transporter trace of the last person, but it is normal, so they start going through people and eventually find a person who used the transporter several days ago - and then they manage to find some anomaly. Although the rest of the evidence speaks against their hypothesis.
Then they try to confirm that Data tampered with the probe signal. They cannot confirm it, but Geordi manages to find several pictures which look like it and conjectures that perhaps Data took all of these and combined them into one image, changing arbitrarily their parameters. He also shows several places on the picture where pixels "are not right".
Crusher's plants, let's say, really did grow faster. But then finally they find an explanation that has nothing to do with being awake for a day (say, some ingredient got into the soil and experiments confirmed it). But, as it happens in conspiracy theory thinking, everybody forgets that the initial mystery, that started the whole thing - has already been solved.
And conspiracy continues! For decades!
