Google was a very large company at $23B, but hardly a stand-out on the Fortune 500. The megacorps which are the focus of discussion - contemporary FAANG et al - are in an entirely different league, by orders of magnitude.
It really doesn't help your case when you have your own views of what a megacorp is that are way out of whack with the rest of the world. I would recommend you write your blog post math style, where you begin with definitions so that people know what you're talking about.
