It's dead, as far as I can tell.
So there's a whole bunch of improvements actively going on the behind-the-scenes (essentially a Commento v2) and I hope to announce things soon. I know support has been lackluster and I intend to turn that around too. It's certainly not dead :)
Also would love for it to be easier to match the CSS to the host site.
Was running it self-hosted on Cloudron but would be happy to try the paid, hosted product if it worked for me.
I actually sent you two emails.
I will send you another one.
Last commit is last month

Did you buy support from the author? As the author of an unrelated open source project, I receive an enormous amount of messages from people feeling entitled to receive support for free on the pretext it's open source. Answering and following up on those message could well be a full time job in itself except it doesn't pay for my bills
I am sure the creator of Commento is happy you are here exacting vigilante justice against his customers for their imaginary entitlement.
I signed up for a free trial of his commento.io service, and immediately tried to integrate it with my static site.
When I ran into difficulties (bad responses from commento.io) I contacted support.
If I had got it working, I would have gladly paid him, and I would still be paying him.
I think I was within my rights to request a modicum of support during the free trial period for a paid product, and then to not pay for it when I did not receive a response.
In this context, I find your story about some open source project you have to be quite irrelevant.
You can even deploy it relatively painlessly. A little googling brought up an ansible playbook to set it up with minimal configuration: https://github.com/kathawala/commento-ansible-playbook
