I understand that you're trying to dunk on me but I don't get what the point is supposed to be. It's certainly possible to come up with other bad ways to ask the question. If someone was interested in genuinely understanding the public's opinion, rather than including a demand to take some particular perspective, they would ask things like "Do you support online platforms scanning all personal messages for child pornography?" or "If you had to weigh the two, would you consider detection of child pornography or the right to privacy to be a higher priority?" And of course for the latter you’d randomize the order in case people are more or less likely to pick the first option.

I suppose the gold standard would be to present detailed arguments from each side with evidence (if any), for context. Barring that, the original question did seem to provide a rough summary of each side’s position. It may be weighted towards the anti Chat Control side, with the formulation “pro says this, but anti says this, and imagine that you are affected”. So perhaps they could have asked a reverse formulation 50% of the time to be more fair. But the poll was commissioned by Breyer, and of course he wanted to bolster his position.

Your context-free formulation on the other hand provides no information for voters to weigh. Privacy or child porn detection? Well I guess I’ll pick child porn detection. Oh, you wanted to do what to my privacy? Never mind!

Even your slightly longer formulation doesn’t really explain what scanning means and how that might affect people and society. Most people aren’t familiar enough with technical and legal details to dig into the implications without added context.
