This is an attempt (which according to some of the comments here quite succeed) to create a story where there is no story.
Should Google Cloud aim to be better and bigger? Sure. Should Google / Alphabet execs need to discuss challenges and strategy? Sure.

GCP produce new products and features every week [1]
At my company, we use all major 3 clouds. The GCP support is super fast. The GCP price is better than other two.
Google indeed has a learning curve as a company, and that is at the area of selling to the enterprise. By its DNA, Google is an engineering company, and it takes years to understand how to "attack" the market, build teams of sales, marketing, and all the supporting infrastructure, and they do it.
Time will tell how successful they are, but I cannot see any option for them to shut down this great platform known as GCP. It simply make no sense.
There is a trend in the media in the recent months to rant about Google by all means and angles, and I tend to think this article is just one of those.
