I mostly work on Windows apps. People still complain when software drops support of Windows 7 released in 2009, or Windows 8 released in 2012. Despite none of them are supported by Microsoft.
It'd be a more fair comparison to take into account Windows 7's EOL which was just a year ago IIRC if you coughed up Extended Support money, its broad install base, and it being the last actually truly decent Windows that had a consistent UI across the place and no ads.
