Once a (freely available) file is downloaded onto a computer that I own & control, they don't have any legal right to restrict what I do with those file(s), as long as I don't generate any derivative works. Using the font in a terminal or editor does not constitute a derivative work. For example, I can use this as my terminal font on my Debian machine, and write code using it, but I can't post a screenshot of that terminal or code to Twitter.
