Indeed, it’s because people use an editor that isn’t designed for editing csv to edit csv. Every csv files is a text file, but not every text file is a csv file, but people use text editors to edit them. A csv editor would forbid you from entering that quote, automatically add a matching one, ask you for your intentions, or whatever, but it shouldn’t silently corrupt your file. A spreadsheet-like UI, but without formulas, automatic single header row, etc. would be a better UI for csv files. If you use zip to edit a .xlsx or .docx file, you easily get an invalid file, too.
