People just have to get over the shock first. Those who say they are done with Ark will return after a while. People complained about the game being unstable and a lot of other technical issues. What is being done now is quite simply a repair of the game. But not only that. It will be a new experience. At the same time, it will also be a base for further development of the game for the next several years. What people choose to overlook, or for other reasons refuse to realize, is how much content, innovation and graphical power they get. As well as brand new servers. But.. It comes with a price. You have to give up years of hard work.
We must not forget that this is a company. The economy must be balanced. Like most games that get remastered, they cost money. It has almost been 8 years since Ark was released. I would think that is an acceptable amount of time. Even if it costs money. And if you look at it objectively, I think you can see it too.
When it comes to paying for the Remastered DLC. Look above. It is exactly the same financially. Don't forget the projects that are underway, regarding the expansion of Ark's business model. The alternative would be alot of microtransaction an half the effort.
