Nope, that would make it a very stupid analogy.
But IBM is just a tiny shadow of their former glory, of almost complete dominance of business computers of any size.
According to the article Google/Alphabet is losing their leadership position too, in much the same way.
They have a stranglehold on enterprise computing after they ate redhat, and they still make insane mainframes, they've just left the consumer world (which makes sense given their name i guess)
I wouldn't go that far, there's been a mass exodus from Redhat and they're hardly the only game in town when it comes to mainframes. You do have a point though.
