What does it mean "Dead Project" ??

Let me quote the Apollo BTC "Getting Started document"

----------------------------------
The Apollo Full Node runs the latest release binaries from bitcoincore.org, and is automatically configured and setup at the system level. It will start syncing a clean chain state from block 0 on your nvme SSD on first boot, and is capable of downloading a full unpruned node on its 500 GB drive with a 1-2 year buffer. This is the core that will enable us to release additional apps and services in the coming months and years (solo mining, block explorer, Lightning network all planned in the short term), and allow you the user to verify your own transactions and chain state without needing to trust anyone else.
-----------------------------------------------------------------------------------

Solo  mining, block explorer, Lightning network and such have been promised for a long time, and in ("short term"),   and having the chance to solo mining my own node was one of the features for which I decided to buy an Apollo.

So I can understand the difficulties, delays, all is legit,...but I cannot accept a "dead project", I would like to have answers to this.
It does not satisfy the premises underlying the moral contract between the seller and the customer.

Is there a responsible who can answer, please?

I'm kindly inviting the one who is responsible of this project to give clarification to all of us.

Thank you very much.
