Imagine trying to read manga like this.
The only thing that’s more sad than this guided view feature is the thought that somewhere at Crunchyroll there is someone whose responsibility it is to manually decide and edit these zoom areas, page after page.
Most likely they know very well that what they’re doing is completely useless and will never be used by anyone. But it’s not their decision.
And if that’s not sad, I don’t know what is.
