Short update on the issue above: it has become clear that Sywert and 2 partners, while pretending all was 'not for profit' made over 20 million (20% margin of profit as the total order was 100 million). Apparently, the prince and many others shared their contacts or spend many hours trying to help, while these three were keeping up the appearance that it was all done to help the health professionals out of their good hearts while at the same time creating various business structures to keep the money they made out of sight.
In one of the prince's earlier replies he says that he most likely would not have helped out, had he known it wasn't not-for-profit; so, he must feel 'used' in a way - and now things have become clear probably also feeling bad about coming to his defense (although he tried to argue that he didn't; but he cannot ignore that he decided to contribute to this discussion while he normally doesn't, so it did touch a nerve).
Earlier this week someone asked: "So, Royal Highness, now the facts are clear (9 million euros [N.B. this is the amount for Sywert]) do you have some confidence again in the national press?"
To which
his short response was: "Yes, certainly"
I also found this '
letter to prince Constantijn' that is rather critical and suggests (incorrectly if you ask me but by somewhat defending Sywert in the first place, he inserted himself in this discussion) that the prince has been helping Sywert coming up with strategies to make most money and dodge questions in the press. His uncle Pieter van Vollenhoven is presented as contrast stating: "Uncle Pieter will not help Sywert and his business partners" based on
a tweet by PvV in which he stated: "I sincerely hope that we can tackle these kinds of profits at the expense of society, in addition to publishing about it. I'm not against profit, but I may old-fashioned in still like the words decency and integrity."
Edit:
an earlier tweet by Pieter van Vollenhoven when the media had just found out that Sywert and partners had made a profit of at least 13 million; he referenced 'decency and integrity' and suggested that these allegiations would lead to a serious investigation. So, a rather different tone than Constantijn's who started talking about cancel culture.
N.B. While all of this is a rather big issue in the Dutch media, the prince's limited role is not.
