I moved my parents from Windows 10, MS Office, Edge, Starpage.com to Kubuntu, ONLYOFFICE, Thunderbird, Firefox, qwant.com.

Most questions came because of the Outlook to Thunderbird switch. I can attribute zero questions to KDE. Though I said the new System is called Linux, they refer to it as Windows 11. ¯\_ (ツ)_/¯
