I think it's unclear what the results would be. For instance, and I honestly don't know, if gmail was split out would it still be able to be free? Or would they start charging for it?
Google workspace is expensive and a big money maker on any scale - except compared to the Google ad machine. This would be a very successful independent business and killing free gmail would not necessarily be a bad move.
Having to hire actual people for Customer Service and treat the whole thing like a business might be a novel concept for them, but they should be able to manage it. :)
