One of Google Search’s oldest and best-known features, cache links, are being retired. Best known by the “Cached” button, those are a snapshot of a web page the last time Google indexed it. However, according to Google, they’re no longer required.
“It was meant for helping people access pages when way back, you often couldn’t depend on a page loading,” Google’s Danny Sullivan wrote. “These days, things have greatly improved. So, it was decided to retire it.”
Beyond that, the money is still going to Google, Yandex, Brave, Bing etc via API payments. If they actually created their own search engine that was any good I’d be more inclined to pay for access.

Edit: They do claim to have their own small indexes (Teclis and TinyGem) that they sell API access to, but I’m doubtful it adds significant value.
