It's not saying "never ever ever ever use 'very'" or "if you want to use 'very', these are always the words you should use, no matter the context".
It's a gentle nudge to remind us that often "very" is something that we reach for because we are too lazy to come up with a more expressive word. The words the site comes up with won't be appropriate for every context where you'd otherwise just prefix a "very". That's fine. It's a starting point, not the end-all be-all. And sometimes a "very" ends up being the way to go. That's also fine.
