It is impossible to verify anything in this article. For example "In recent internal discussions and public remarks". Where are these public remarks? How did this author get access to internal discussions? I rate this article as clickbait nonsense.
It does seem like Salesforce relies on Agentforce and therefore doesn't need as much support stuff. But the pressure was also to “reduce heads”, which is a bit of a tone-deaf way to describe firing thousands of people.
