Thank you for the post and the GitHub link.
Stands to reason team members would be moving around on a project that was started at the end of 2013 which makes it nearly 6 years old.
Even though Doge started out as a joke it really impacted crypto-world a lot. I hope Doge has a bright future ahead of it.
I certainly believe in Dogecoin's future, I firmly believe Dogecoin will remain to exist as long as Bitcoin exist. No matter what will happen with other altcoins, Dogecoin will survive because we are using it, and I am using it, more than Bitcoin for doing the transactions.
as long as the team keeps active updating the blockchain, I am fine with them being inactive here.
