My hypothesis is that all this caused by data science, machine learning, and deep learning. R is quite cryptic and hard to learn. Almost all new libraries for DS are written in Python. Also, in favor of this hypothesis is that rich countries are ahead of the curve in DS adoption. It's much harder to find a DS job in a developing or not so wealthy developed country than in US.
