This was leaked, not intentionally made public.
And it all makes sense -- the people producing these types of business analyses are world-class experts in their fields (the business strategy not just the tech), and are paid handsomely for that.
The "regular stuff" people consume is written by journalists who are usually a bit more "jack of all trades master of none". A journalist might cover the entire consumer tech industry, not LLM's specifically. They can't produce this kind of analysis, nor should we expect them to.
Industry experts are extremely valuable for a reason, and they don't bother writing analyses for public media since it doesn't pay as well.
