I CAN'T COPY TEXT FROM PDF? [SOLVED]

So, I was working on a writing project and was doing some research.

I then came across this pdf document I couldn't copy text from due to security settings.

As a solution seeker, I went online and came across this website where I can remove the security settings and copy the text from the document.

Happy viewing!!!
