In 2006, developers of SQLite changed the default temporary file prefix from 'sqlite_' to 'etilqs_' after receiving numerous complaints from Windows users. The issue arose when McAfee integrated SQLite into their antivirus product, causing temp files to clutter the 'c:/temp' directory with the 'sqlite' name. Frustrated users attempted to contact SQLite developers, prompting the change to deter such calls. This has been a topic of discussion within the developer community, illustrating the common struggle developers face with user feedback and the indirect consequences of software integrations.
