Uhurr.. that's your excuse, it got 7.5/9 FFS.
You forget that air forces create requirements by basing it on their most advanced aircraft in operation. In the Swiss case it's the Hornet. And all their releases have proven that they compared the three jets to the Hornet.
So any SA, networking etc, will be based on what the Hornet already does. Which means it's unlikely the Swiss considered sensor fusion as a metric. In fact SF will be part of a different points table that allows OEMs to show off "future capability", information which they obviously did not release. It's also the reason why Data Dissemination got very low scores, because the Hornet also uses Link 16.
Even with the recent tenders, the Swiss and Finnish are comparing new jets with the Hornets. And this gives the F-35 an unfair advantage since the Hornets are so old that they are helpless against it. If for example the Rafale has the capability to defeat the F-35 in A-A combat, the Swiss and Finnish will never know it, so it's not necessary that they are making the best decision. Similarly they do not know how well the F-35 will do against the Su-57 either. And we already know for a fact that the Hornet cannot match the Flanker. So, all they know is the F-35 is far superior to the Hornet due to stealth and that's how they are going to make their decision.
What's interesting is the Swiss paid particular attention to stealth and NCW, and not data fusion, in the F-35's testimonial. So that means the other competitors had already accomplished quite a bit in this field, so it became unimportant enough to not be specifically flagged alongside stealth.
