IIRC, around 2008-2009, "most recent" was the only kind of feed, and within the span of a couple years, they added their "personalized" feed but would let you switch between the two freely (and the setting would persist), and not much later, the setting would no longer persist.
The moral panic over feed ranking models will seem to history as quaint as the moral panic over the telegraph and the train.
If your new technology isn't attracting a swarm of moral gnats buzzing about it corrupting the youth, are you even making something impactful?
How does it hurt you by requiring social media to offer a working chronological sort?
I think even casual users understand the appeal of having both options and wouldn't want to lose it, assuming they discover it.
I agree with the judge. We are not obligated to suffer the degeneracy of the hyper-optimized algorithm with no alternative.
Just because you have never experienced the utility of working chronological sort doesn't mean it doesn't exist.
