The comment you're replying to is a bit ambiguous. Did they mean don't put anything directly in /usr (i.e. except /usr/local)? Or did they mean don't put anything anywhere under /usr? Both are consistent with my comment. Personally, I stopped using even /usr/local (or /opt) many years ago. If it's not managed by the operating system then it goes in my home directory (except a few things in /etc that have to go there).
