Yes, Webnovel is a business. That's why they try to get the most for giving the least. When I was little, I played Poptropica online for free. And then they started restricting things that used to be free so that you had to pay for it. This app is doing the same thing, and you can't really blame them for trying to make more profit. I don't have the privilege of being able to pay for coins or whatever, so I'm a free reader, and although I'm not happy about the changes, I have no right to antagonize Webnovel for them. I've just gotta suck it up and sadly accept it.
The only thing about the changes that irks me is that they're so sudden, without warning (I rarely read the forum) that I'm confused and surprised when I open the app to see them for the first time. It's always a sad experience to see that they've taken away another source of free SS. But they have every right to do so.
The only legit complaint I have is that they provide these novels and expect people to pay for them when the quality is deplorable. If you're going to sell something, at least make sure it meets some kind of standard! I'm not talking about every novel, as I haven't read every novel, but take It's Not Easy to be a Man After Travelling to the Future, for example. After Henyee took over translating this novel, it's been almost painful to read the story I love, as it seems like they have no editor looking over the released chapters, or even a translator reading them over again. I even posted on the forum about this because it was so bad, and Henyee responded that they were using the same editor as the previous translator, which I was surprised about since the quality had always been pretty good and consistent in the past. I found this increasingly harder to believe as the quality of the translations continued to plummet. Later on, they announced that the editor had disappeared (notice deleted already) and asked for applicants but then never said anything again, and their level of quality persisted. I had applied, and they'd given me an unedited chapter to edit. Later, they never responded to me, and I saw the same chapter go up even worse than the way they had given it to me to edit. WTH? What's with this quality!? But anyway, I've digressed. Tl;dr: If they are taking away free sources of reading and expect to receive more profit, then I think they should at least watch the quality of the services they're selling. That's the end of my long rambling.
