I don't think that's true, or at least it's no longer true: RHEL 8 does not ship with Python 2 by default. https://developers.redhat.com/blog/2018/11/14/python-in-rhel... Red Hat software that depends on Python, like yum, is in Python 3.

I think it is true (as of pretty recently) that Red Hat is the only company employing a Python core dev to work on Python core dev stuff full time (see https://discuss.python.org/t/official-list-of-core-developer...). But the core dev team is focused on Python 3, so that isn't a sign of Red Hat's Python 2 commitment either.
