Well, it is not a paper "from" University of Zürich - only one of the authors appears to be from ETH Zürich actually, and not from University of Zürich.
Does it hurts?
It is usual that the research is first awarded to the uni of the research leader, which is here M. Gervais from ETH Zürich.
ETH Zurich is a science, technology, engineering and mathematics university in the city of Zürich, Switzerland... In the 2020 edition of the QS World University Rankings ETH Zurich has been ranked 6th in the world (2nd in Europe after the University of Oxford),[6] which represents a one place improvement compared to the 2019 edition,[7] and is also ranked 13th in the world by the Times Higher Education World Rankings 2018 (4th in Europe after Oxbridge and Imperial College London).But if you prefer, you can award this research to the third school: HEC Paris... Which is one of the most famous and prestigious french shool of business, ask Maciej if you don't believe me
No seriously Cookiess, do not play this denial game here...
It is interesting how (over)confident you are - here is the explanation - do read carefully:
1. University of Zürich is a separate entity from ETH Zürich - you are still mixing them up. The named author is (or was at the time the paper was published) from ETH Zürich and not from University of Zürich, as claimed by you.
2. Nobody tried to say that ETH Zürich is bad - it is indeed famous and more known than the University of Zürich. You simply misunderstood and thought that I am trying to marginalise its importance / quality, while I was just pointing to another mistake of your "research".
3. Just to correct you again: the grant holder/hosting laboratory head is normally the last author of a research paper. Hence the research gets assigned normally to the last author's institution (and not first), unless it is a joint research / review paper of fellow peers where this matters less (for more information, please read the following article from one of the most famous / quoted science journals out there (next to Nature):

Again, I am not trying to dispute the quality of the institutions, I am simply observing that your attempts to understand and convey even the simplest facts are full of your mistakes and misinterpretations.
