This is (hopefully) a summary of what has been going on with NeosVR since November 2021 (written by a community member).
There's a quick F.A.Q. here, as well as some more fleshed out details with links. If anyone wants to add/change some stuff, feel free to.
Neos has not had any feature updates since November 2021 due to disagreements that Karel Hulec, the CEO of Solirax (the company behind Neos), and the rest of the Neos team, led by Frooxius (Tomáš Mariančík), had with the direction of Neos, and the roles that each member had. This led the Neos team to stop working on Neos until these disagreements were resolved.
After some public escalations with the situaiton, the Neos team decided that they no longer wanted to work with Karel.
No-one knows.
For more info on that, please see Resonite.md.
NeosVR currently has a cryptocurrency tied to it called "Neos Credits" (NCR). The importance/priority of this cryptocurrency was only one of multiple equal reasons the Neos team disagreed with Karel.
