I read over the Dutch interview translation, which I think is the one you're referring to, and I didn't see any specific mention of the veto. ETH said that he was happy to have Ashworth, Wilcox and Vivell to support him and that they made decisions together. However, he did also say that signings have always been a joint decision (not just since the new structure came in place), made in consultation with Murtough and the scouting team.
"We determine the composition of the selection together with the sporting director, and we carry out that process together. We have to agree with each other, otherwise it won't happen. That's how it was at Ajax. Very simple actually. In today's football, as a manager you can no longer scout yourself. It doesn't work that way anymore."
My reading of the interview doesn't make it sound to me like things have changed that much in terms of his influence, aside from there being more people (Ashworth, Wilcox and Vivell) to support ETH.
You're right that ETH said De Ligt was suggested by someone else this summer, though he did also acknowledge that he tried to sign him 2 years ago when he chose Bayern. With that in mind, our scouting team almost certainly would have known that ETH is a fan of the player and would back the signing, though it at least suggests there are others that think he would be a good signing.
Yoro was a step in the right direction. Leny was very well known still, so I would also like to see some lesser known players brought in also. I'm hoping we might see some of those after our priority transfers have been brought in.
