There no longer is an enterprise version, what runs on Azure is the exact same Citus that you can run yourself. We even invested in Patroni, to make it easier for the community to self-host Citus with HA setups.
While we obviously want people using Citus on Azure, having Citus as a viable open-source choice is our path to achieving that. I wasn't part of the company when the acquisition happened so can't speak to that, but I can imagine how that could have made sales at the transition time unclear.
Personally I would also like to add, that the team is full of long term open-source contributors. We contribute both to PostgreSQL and projects around it (like pgbouncer). I understand and respect your reservation, but wanted to share my perspective on it.
