Ask HN: Is Google Scholar restricting ChatGPT4 access?

ChatGPT4 tells me it cannot access Google Scholar directly, but does not provide a specific reason.

How long has this been true? Is it possibly related to OpenAI's relationship with Microsoft? Or is it possible related to Google throttling OpenAI? Or some other reason that I'm missing?

I find Google Scholar to be the best search engine for academic social science papers, so I find this limitation to be significant. I have not been able to find an explanation online.
