tl;dr:

- Mozilla fired the developers and mothballed the project

- But wants to keep it around as a museum piece

All ongoing development is happening in the fork.

I was very sad when that happened. There were a lot of language communities organizing their efforts around that project too.

Yeah, they really dumped them in it, fortunately the devs are keeping it all going at coqui.ai and are really supportive of any community that got abandoned by Moz.

any idea how they are financed?

Looks like after nvidia 1.5m grant devs returned back ;)
