Cybersecurity - Memes

I understand why stored information, such as passwords, usernames, stuff like that, has to have a max character count.

What I don't get is why so many people are so daft as to let stuff like this happen, and not even put the maximum password length anywhere people can obviously see it.

If you tell me what the maximum limit is, I'll be able to keep my password shorter than that.

But no.... Password minimum length is shown, symbols, numbers and special character requirements are plainly stated. Maximums? Ha.
