I think that this commentary is well written overall.

Unfortunately, it lacks some important facts that would have assisted the readers' fair judgements.

So, I have posted my post-publication peer review (PPPR), which also contains the aforementioned facts, onto PubPeer (https://pubpeer.com/publications/0BBC818513066058DB929595CE7C32/comments/120820).

It would be strongly recommended to read the PPPR as well before or after reading this commentary, in order to have unbiased opinions on its subjects.
