- The 2.9 and earlier 'ansible' you got when running `pip install ansible` was built from the ansible/ansible repo on GitHub.
- That repo is now building the package 'ansible-core' (well, temporarily 'ansible-base'), which just has the core Python that runs the 'engine' behind Ansible.
- The 'ansible' you get with `pip install ansible` is now at 3.0.0, and includes all the 'batteries included' modules and such that used to be part of Ansible 2.9 and earlier (and many new things too), which come from 'community collections' that are on https://galaxy.ansible.com
- Separately, Red Hat sells services/licensing around the 'Ansible Automation Platform', which packages up ansible differently, and uses collections that are stored in a curated 'Automation Hub' which is similar to, but separate from, https://galaxy.ansible.com
