No need. Just, when you wanna argue, exaggerations not exactly something you wanna lead with.
And still -- being a big company doesn't mean that profit today can't and won't go away in the next few years. After all, only 12% or so of the original fortune 500 companies are still around today, compared to what they were in 1955.
While it's good to keep up with numbers and current flow now, it's also important to plan for things long-term and continuing to find ways to maintain that current status. Hence is why I mentioned that a company like Naver still continues to focus on ads, even if it's not to a large extent. They're making 700 million dollars/1 billion a year now, and maybe they're not spending all of the profits they gain from their outlets (Line Webtoons included). Still doesn't cover what could happen in the future.
Course, that's all hypothetical. No one knows what might happen to Naver 10, 20, even 30 year down the line. Because these things are unpredictable. However, preparing for some of that is just another business method, and in doing so, a lot of big businesses will think about the changes they have to make and the progress they're seeing so far.
They're doing good by not spending all of their profits. And they're also doing good by investing in the different parts that make up their possible income.
They're covering all basis because they're a big company and because they have so much to gain and lose. So, in order to maintain the profit they're gaining, they look at all fronts.
With all that said, I would personally like to see more site improvements from Webtoons. Particularly in the case where they update the comic uploading page and move the delete button a little further down. You'd think with all that money they're seemingly making, they could afford to fix up the site so that people don't accidentally delete their entire works when they're just trying to upload.
