Ok, grammar nazi alert. Who uses the word academical? I had to google it just to confirm it is indeed a word, albeit a rarely used one that is indistinguishable from the simpler, and in my opinion, the proper word, “academic”.
That is a category of non-native speaker that I hadn't considered until you mentioned it. A bot. Perhaps the author of this post, and the article I mentioned aren't human at all. They could be bots. Sorry for being robophobical. These are anxious times we are in.
A bit like saying “that’s nonsensical” vs “that’s nonsense’. https://wikidiff.com/academic/academical
