if *that* is what is supposed to make DNF faster it's just a lie

This is not the only thing that DNF does differently to try to make package installations and updates go faster (or appear to go faster).  Calling the developers liers doesn't help the situation any.
 
if i am really interested in updates now i do "yum clean metadata && yum upgrade"
for many years simply because you don't know how accurat you metadata are

Sure, but you have to understand -- you're a power user.  You know enough to do this in yum for your particular use case, which means you probably know enough to change the DNF settings with regards to cron-based metadata retrieval.  What I think you're missing (and frankly, seem to miss in the lot of fedora-devel discussions you take part in) is that Fedora isn't engineered around *your* particular needs.  We do things mostly by consensus, and aim to make it a pleasant experience for the *average* user (or whatever we have in the Fedora community that approximates an average user), and not just for power users with very specific needs and requirements.

Whether you like it or not, one of the most common complaints about yum (especially from people coming from another package management system) is that it seems slow because of the necessity to download the metadata.  The DNF developers -- in trying to address this common complaint -- had solved it by handling metadata in a different way.  They've also added settings so that power users like you and I can tune it to better fit our particular needs.
 

and *no* traffic is not cheap everywhere, by far not

I probably understand this better than a lot of people on this list, as I've been on a bandwidth-limited connection for the past nine years.  Only in the past month have I been able to get high speed internet in my home that wasn't limited to a few gigabytes per month.  So yes, I completely understand that traffic isn't cheap (or fast) everywhere.
