That'd be a very misleading survey question, as it heavily implies they're selling it to other developers the user didn't engage with at all.

"Are you aware that connecting app Foo to your bank account gives app Foo access to your transactions?" is likely to be met with a resounding "no shit, that's the point..."

So your claim is that the average person on the street understands that if they send someone money on Venmo once, then Venmo gets 24 months of their bank account history?

I find this implausible. You have an empirical claim. You're welcome to test it.
