From what I personally have seen, this sort of guidance remains. When companies do use things like Google Docs or Microsoft Office365, they likely have some specific contract in place with Google / Microsoft / etc., that the company's legal team has decided they are happy with.
I anticipate that the same will eventually be true of ChatGPT and such, that there will be some paid corporate offering with contract terms that make the company lawyers happy.
Most of my career has been with larger companies, often with high data sensitivity; I can easily imagine that some smaller and/or less data-sensitive companies might not care about any of this.
