Angko I agree with you that webnovel needs to offer another option that better supports its multiple goals. I think they agree too, that's why they offered the subscription service.
When I pay money to webnovel, I personally am not paying for a finished product, like I get on Kindle; I am paying for a product to be finished. I see something I like and I want to see it continue, both for me and for others. So I reward both the author/translator and the mechanism (webnovel) that allows me to find such work by buying SS, and if I really like it, by buying Privilege.
While it might be nice for the newly contracted authors to get more money via webnovel, for most of them the little money they get is better than any other option for them. Authors on Kindle don't get any money until a book is finished and the reader is paying for a finished product. If the goal of the author is to get readers (and comments/help) and not to get money, then they shouldn't have signed a contract with webnovel and instead published unsigned and for free here or somewhere else. Webnovel contracts at least allow those authors to get supported by those who want to.
