Free stuff, full data harvest — the prize is never the prize.

means Something that reveals the truth of a situation without meaning to — or a free item used to lure you in, usually with strings attached.

from Straightforward compound of 'give' + 'away,' first used in the 1870s for literally giving something away free. The 'involuntary disclosure' sense (as in 'your face was a dead giveaway') emerged later, once people noticed that things handed over too freely — information, tells, expressions — reveal more than intended.
