"X is bad for you."
"Turns out X is actually great for you and it was Big Y spreading misinformation."
"Actually, turns out X is only terrible for dogs but nobody remembers that part of the story."
"To the disappointment of my Asian parents, it turned out I hadn't shipped with the firmware needed to support violin playing."
If that turns out to be recent trend in rhetoric, that is mildly surprising.
When people make ironic uses of some rhetorical device, it inevitably happens that a number of people don't get the humor and start using it unironically, like that's the correct, casual thing to use for that situation.
Puts me in mind of Trump being asked about the lack of evacuation plans around the Iran war, his response was "because it happened to all very quickly", as if it were a force of nature rather than something the administration had control over.
"I gotta tell you, I am loving this Yada Yada thing. You know, I can gloss over my whole life story."
"No I mentioned the bisque."
