That was one tweet in a tweet thread from a… guy who is a bit of a character and does stuff with AWS. He pokes a fair bit of fun at Amazon and others in the cloud.
And then, when the sales teams talk about it, IBM Cloud Private is too long to say again and again… so they start calling it by its abbreviations… not IBMCP but rather ICP… and you start picturing the sales team wearing clown makeup. And when they talk about Machine Learning you share Using AI to Find Where Clowns End and Juggalos Begin with the devops guy sitting next to you and get some muffled chuckles.
Not that those events have ever happened… or would be admitted to.
