The KDE Project has issued a Security Advisory: Do not use uninstall.exe July 21, 2019 https://linuxreviews.org/Windows_users_of_KDE_applications:_Do_not_uninstall.exe
@mirimir, I think it's been that way for quite some time. For example, https://forum.kde.org/viewforum.php?f=59
I'm sure that it has. Just never had a clue. And not sure what the point is. But then, I find KDE annoying and overweight on Linux, so hey.
