How to deal with people giving reviews to the teaching?

Piya Tan is a renown and respectable Buddhist scholar and lay Dhamma teacher

to some it may come as a surprise but Tipitaka is not a literal Buddhavacana, it's a man's creation, especially the mythical motifs, based on the teachings of the historical Buddha

just as the Bible is not the literal word of God but a creation of men, as has been demonstrated by the extensive biblical research on many levels

consequently Mahaparinibbana sutta was not composed or narrated by the Buddha, but is a result of literary efforts of subsequent generations of Buddhists

nevertheless this fact doesn't devaluate and doesn't invalidate this corpus of texts

on how to deal with such people my advice is to apply towards them all four brahmaviharas

It's typical human nature why forum like this or chiritinity or religion exists and consequently their misunderstandings.

That's why some buddhist sectors keep in very hermited to preserve authority and the jewel intact.

Buddha's teaching knowledge alone can be a hinderance to seeing what he realized. It's not knowledge building. You have to meditate and experience. When you build a knowledge while have a strong ego, which ironically it means it can be a danger and might better off not studying at all.

Buddha said everything in simple terms 2500 years ago. That's all you need to know. Wisdom and whaever written in sutras as knowledge, interpretation, findings, they all come at once without studying them just when one see the glimpse of the truth.

That's the best way to deal with it.

Any commentary on the Suttas by anyone is a personal opinion or explanation on that Sutta. If your opinion differs than just leave aside what you do not find agreeable.

Any commentary on the Suttas by anyone is a personal opinion. For example, I personally rarely agree with the commentaries of Piya Tan. Similarly, often other people do not agree with my personal views of the suttas.

In Buddhism, we can only deal with this using non-attachment because, in reality, there is not much consensus in Buddhism. My impression is many Buddhist groups & sects have idiosyncratic & worldly agendas.

It is only by letting go of craving & attachment can the true reality of Buddha-Dhamma be known.

In the suttas, we see the Buddha regarding a wise person one who reflects that grasping and insisting firmly on a view would create clashes and disputes with those who hold a different view. "Where there is a dispute, quarreling. Where there is quarreling, annoyance. Where there is annoyance, frustration.' Envisioning for himself clash, dispute, quarreling, annoyance, frustration, he both abandons that view and does not cling to another view. Thus there is the abandoning of these views; thus there is the relinquishing of these views." (MN I 500)

He also sets an example when saying:

“Bhikkhus, I do not dispute with the world; rather, it is the world that disputes with me. A proponent of the Dhamma does not dispute with anyone in the world. Of that which the wise in the world agree upon as not existing, I too say that it does not exist. And of that which the wise in the world agree upon as existing, I too say that it exists.

-- SN 22.94

Also, as a side note, the language used in the article, it's propositions are that of hypothesis. In other words, the author is speculating about it, conducting an inquiry (e.g. note the use of "possibly") and drawing parallels -- like any historian would do. So, he does not seem to be defending or promoting any position as a fact. And because he is just offering alternatives, he is not really leading or misleading. After all, as a matter of principle, when an author offers alternative possibilities (e.g. "it's possible that a person is guilty of certain crime"), he/she is not accounted for readers who decide to remove the provisory character of the statement without reflection and simply believe the possibility to be true (e.g. "the person is certainly guilty of certain crime"). In this way, readers can mislead themselves but the author is not responsible for it.

someone might get caught up in the wrong side of the isle after reading some person's foolish efforts

There will always be reviews coming from writers who are not comfortable with things like heavens and divine beings. People with materialistic views will be drawn to such articles naturally. If you get angry at them, you might be clinging to the Dhamma as "my religion" or "my belief".

Having everybody to believe in the same thing is not the goal and wanting that to happen will only frustrate you. The goal is to use the Dhamma to attain Nibbana. You can certainly help others to stay away from misinformation while doing that, but it should come from compassion, not clinging or aversion.
