Yes, misleading metrics, indeed, including the traditional impact factor itself!
Again, see a recent paper about it here:

Why there should be an impact factor for a journal or for an author?
Unfortunately, classification of everything (including women and men) is one of the drawbacks of the capitalist system to make everything for profit; we classify journals and people in term of profit and money!
We classify journals, even if subjectively, it does not matter, because the ends justify the means!
I decided not to submit to any journal with impact factor!
Some of the so-called scientists are closed minded and insist on the impact factor despite its innumerable vices.
