I remember reading some crank on slashdot decades ago seriously claiming that Windows was not an operating system. This type of argument hasn’t gotten any more intelligent since.
Following up, I see that's not really what the author was trying to say: it's that for a growing number of purposes, like gluing together two languages that aren't C, that the C ABI is still dominating things where the C language shouldn't even be involved.
Write clickbait, get kneejerk. I guess some other things are at least as old as C.
