This is sad news and a little concerning that no explanation is being given. On the face of it, it looks like a complete disregard for the community - I hope that's not true. What is true is that community engagement on forums like this has declined in recent years. Some of that decline is a result of AI. I know that this site has been scraped by LLM bots and, as a result, people seeking answers don't need to visit the site if an AI agent can provide the answer.
Just to let you know, I have no intention of closing or suspending this forum any time soon.
