The first part of the Wilmer&Maria video is very leadable, but I think the article refers to artistry like the ones at 2:33 or 3:00 - this is not for social dance for sure. She acts on her own, she has learned by heart what to do, this is not leadable. The same is well-known with some bachata couples (e.g. Melvin&Gatica). One could say "If lead raises his left little finger then follow is expected to do a backflip", but I wouldn't call this lead & follow, this is choreo and not for the social floor. I understand the writer is uncomfortable with this development.
But honestly how could it be different? Pro dancers must live from dancing, so they must teach (even if they are didactically bad), and most students are beginners & improvers, you see that in every dance school: the pyramid gets thinner to the top. And beginners get impressed by artistry, not by good grounded stepping (which they don't see). The million clicks in social media do not even come from dancers. This is about economy.
Unfortunately the writer also plays the authenticity card in the third paragraph. I understand this is a valuable thing, but in general the world does never maintain that. We don't eat kebab like they do in Turkey, we don't eat pizza like they do in Naples because we adapt it to our other needs, and our local, personal needs always top over what some 10.000 km away people think of it. If you export your thing to the world it gets changed. One can regret that, and there are always people who are interested in the original thing and maintain it, but most start dancing with other reasons than to maintain a culture they have never been to.
