“vortex.gg”, the cloud gaming service, now has a home page that says they are no longer accepting new customers. Their blog is a Google Stadia ad. Did they get acquired, or are they shutting down, or what?

Cloud gaming companies seem to come in two flavors - overpriced, like Shadow, and loss leaders, like Stadia. Unclear that anybody does this profitably, and in the last few years, many players have dropped out. Is this a viable business?
