I know that there are domains that are mostly on Python 2, and of course you'll always have legacy / unmaintained things lying around. But "zeee majoritie is Python 2.7!!1111" does not become true by some people chanting it over and over again. The simple fact that frameworks and libraries are moving away from Python 2 already proves that the majority does, in fact, not use Python 2. Otherwise maintainers would also be in an approximate majority to block/veto such changes.
Maybe check your language a little? "zee majoritie", "chanting it over and over" etc, gets tired and offensive soon.
That aside, there are actual numbers for Pypi supporting that. What do you have to counter these?

It just proves that after 7+ years, some frameworks and libs managed to justify porting over to 3 too. It doesn't say much about which is used more.
99% of Pypi traffic is composed of mirrors and bots. Python 3 toolchains are more likely to use tools like devpi, wheel, and Docker to cache their packages, while Python 2 toolchains are often going to hit Pypi directly.
We're concerned about which version has the majority of users, not about which has more downloads on Pypi.
Every OpenStack build, for example, pulls in hundreds of packages from PyPi.
In terms of real-world use, all of the Python devs I personally know moved to Python 3.
As seen with Django, they were able to support both. I've been able to support both with the code base to some of my projects as well.
Currently I have one project I'd like to be Python3, but it will involve forking two dependencies (owfs and phidgets) and having them support Py3 (phidgets actually builds and entire python3 tree and installs it and yet you can't import anything from it because it's all python2 syntax -_-)
Python 3 has been out for quite some time. I don't see why everyone is still holding out.

So they are working on it.
