We shouldn't jump on that bandwagon and instead try to explain (for what it is worth) the topic.
I dare say that these images from the SpaceX launch are indeed "CGI". Most modern video equipment is digital. All these images are generated by a computer. The pictures the Flerfers take with their magic P900 cameras are generated by a computer. The text on the screen that we are reading is generated by a computer.
All "CGI".
But that is not what this term is used for in the common everyday language. As most people use it, it means "the data that these images / texts are based on is not real, but invented. Virtual."
And that is not the case here or in the images of the black hole or Earth or the picture you took of your granddaughter's wedding.
So, yes, it is "CGI", because it is made by putting data into a computer and having the machine translate it into an image. It is not "CGI" as in "what we did put into the computer was conjured out of thin air."
