Microsoft Unshipped 27 Bing Search Features.

I clicked for you:

I did ask which features were "unshipped" or removed but I did not hear back.

Unfortunately the Source is a four day old tweet by a CEO with six months on the job that has the same amount of information as the headline. That this is the same CEO championing Windows Co-Pilot, his statement seems like a cry for attention, or an attempt to take credit for other’s work.

It's worse than clickbait, the article doesn't list any of them.

Best I can tell from looking at other sources, They started removing some of the shell integration and at least one of the apps that was shipping with Windows. I suspect now that replay is in full swing they don't need us to talk to the chat anymore, They can directly see what data we're getting from where.
