Yes that is what happened to SO. They now get practically zero questions, zero answers, zero page views, and zero ad revenue. It is their own fault because they froze everyone out of the site and then once LLMs became an alternative, everyone started asking their questions to LLMs. They are now trying to somehow pivot to AI to make revenue again, starting with Stack Overflow for Agents, and now with wordy vacuous blog posts to show off how AI they are.
