I think that comes from the way JavaScript communities (looking at you, React) appeased the "must have functional paradigm" people who actually did not understand what FP brought to the table (for example, React already had a real FP paradigm, Higher Order Components, that nobody used because they didn't understand FP). So we have things like hooks, that hide state in a hidden registry (kinda like the old Singleton pattern, but like all the worst parts of it) and call that functional. If you're looking to Kent C Dodds articles to build your understanding of FP, you're looking in the wrong place. So of course you'll come to wrong conclusions.
