Depends which of the many similar but subtly different things with that name was meant.
In this context, what matters is "how many operations can I get done for a dollar?", and that's still very much improving very fast, albeit not quite as fast as before.
The original formulation was "The complexity for minimum component costs has increased at a rate of roughly a factor of two per year", which stopped being true almost immediately and very soon got mixed up with "performance doubles every 18 months".
Dennard scaling is long dead, as is the clock frequency race; but features are still slowly getting smaller (your own link says so), as is energy consumption per operation. The latter, J/op, is the critical issue for big data centres. Brains are obviously better than transistors at this, and IIRC by that measure transistors are still getting roughly twice as good every 2.6 years.

From the link: "Although miniaturization is still happening, the Moore’s Law standard of doubling the components on a semiconductor chip every two years has been broken"
I'm not saying things aren't getting smaller. I'm saying moores law is broken.
