We can never be sure what the original devs are up to. They don't communicate regularly, but they suddenly come up with improvements out of nowhere. And then again go to shadows.
So they're not communicating doesn't mean they have abandoned the coin. They may be just keep working behind the curtain, giving zero fucks to what we think of them.
Yes, I like their way. Decentralised, privacy. And I do not see a necessity in communicating with a greedy crypto community, it steals their time. And they are not vulnerable this way, as happened with many other coins (bbr, xdn, and others).
