Or they may not understand how PDF works and think that it's the same as paper.
Especially with the "draw a black box over it" method, the text also stops being trivially mouse-selectable (even if CTRL+A might still work).
Another possibility is, of course, that whoever was responsible for this knew exactly what they were doing, but this way they can claim a honest mistake rather than intentionally leaking the data.
A while back I did a little work with a company that were meant to help us improve our security posture. I terminated the contract after they sent me documents in which they’d redacted their own AWS keys using this method.

Yes; that's presumably included in being "amateurish" and "not following proper process".
