I raised that point at Facebook when I joined (I had lived in Finland soon prior and didn’t speak a word of that terrifying language). My back-of-the-SQL estimate was several percentage points of ads were shown to someone who couldn‘t understand them. It took six months for the company to ask someone to investigate further; he confirmed my estimation and had “the most impact anyone junior had within two months of joining the company”.
