AFAIK the developer Dogecoin already abandoned the project years ago and it's going on its own. It's a mere joke but dogecoin still being loved by the people but if there's a rumor that Ethereum foundation is going to take over DOGE means that there will be people that are going to improve its current state. There are people that found it not so good until today so if they ever are going to take Doge, they can do what the people want and improve what they want to improve.
Abandoned or not, no one cares about that.
The most important thing is Dogecoin has been accepted and widely used around the crypto world.
It has very high liquidity, real use cases globally, as you said the coin still being loved and prefered by lots of crypto enthusiasts.
It makes sense and will help Dogecoin maintain its survival over next years.
We can compare that bitcoin having no satoshi until now but there are active developers that are working on its development. You can easily say that no one cares about that but I've read some investors that actually care about that.
Maybe Dogecoin prove that adoption is key for altcoin to be success. We know for now a lot of coins and tokens created, without adoption they not really good in market. Not like Dogecoin.
Adoption is key for cryptocurrency as a whole to become successful.
