I agree. The other day, I had to write a 1-page project proposal for a PhD scholarship and they were giving the font to use and its size, and the margins. I had almost no mathematical symbol to use. One of the professors said that it looks unprofessional to not use Latex. I mean, I could have use Latex and I would have looked like exactly the same given the requirements. I just did it in LibreOffice because that was really the simplest I could have done.
