Everywhere else in Anthropic's interface, yes/no switches show blue when enabled and black when disabled. In the box they're showing about this change the slider shows grey in both states: visit it in preferences to see the difference! It's not just disappointing but also kind of sad that someone went to the effort to do this.
Just did and it behaves as expected for me in the Android app (ie. not the dark pattern you described)
I can confirm it's grey on both sides on the website.
I get blue (on) / black (off) on the website. Or blue / white in light mode.

It was easy to not opt-in, I got prompted before I saw any of this.
I think they should keep the opt-in behavior past Sept 28 personally.
They’re likely A/B testing the interface change, which is why people are getting inconsistent results
It works correctly (blue on, grey off) in the iOS app. I just did it now.
This is probably because there are laws in some countries that restrict how these buttons/switches can look (think cookie banners, where sometimes there is a huge green button to accept, and a tiny greyed out text somewhere for the settings).
Can you provide an example?

This link is not even remotely close to an example of the behavior you described.
