If you are a researcher, you shouldn’t have to ask someone for information that is readily available and particularly for that which you should already have intimate knowledge of.

There’s nothing to discuss. You are clearly biased due to the motivation to defend the publishing body for your research.
Expert scientific bodies all over the globe, including China , Europe , had or have strong criticisms of the MDPI and for very good reasons.
It’s a paper mill where for a fee you can get published in a quarter of the time and work. Yes, the individual journals are the source of the problem but that MDPI constantly includes their crap taints the lot.
