If anyone doubted this project would survive then take a close look at the activity on social channels and on their own website.
Everyone has left - And their vision, or what we should call it, will be broad to life by other projects who are able to mange their project.
The only question left is really, will we see an announcement of them leaving or will they just let it be and hope that a bullmarket will spark some life into the price on their coin.
(Probably the same strategy they used in 2015-2017)
No one will ever tell you "hey we are leaving, good bye". Every projects that are dead are abandoned without any notice. I don't know if there is the case of Cloak but since maybe you know more, it could be. Cloak is/was a very interesting project and I hope you are wrong. I would like to see it going forward. Time will tell, tho.
