It's not difficult to understand why people want to protect their PDF files.
Imagine you are a publisher; you must make sure the copyrights of your books are perfectly protected, because the content equals money to your company. Therefore, you need to protect the PDF file of the book with proper password. Thus it is only accessible to readers who are authorized.

Even though you are not a publisher, you just create a PDF eBook for yourself which you probably don't want to share with others temporarily. By applying a user password for example, you may be somewhat relieved from the worry.

Nevertheless, when some people strive to seek methods to impose restrictions to their PDF file, others, in correspond, pay equivalent efforts to crack PDF password. That's why there are so many PDF password crackers available online. So let's think about why people want to do that.
Of course, it's not appropriate to crack restricted PDF for some illegal use. What about we forgot the password of our own PDF file? Or our friends send us a PDF file to share, but they forget to remove the restriction of the PDF file? These are two typical situations. When passwords become a headache, it's the show time for a PDF password remover.

Many things in the world are controversial. We can't assert some practices are right while others are wrong. So here we can't say it's reasonable to protect PDF, and it's improper to crack PDF password.
