Thanks for your answer.

Well, the condition is there for the user to select which features to install. Is the a way to tweak the condition so it will also work for uninstalling? I have already tried to skip the “Installed” part and it did not change the behavior… ☹

Unlike LaunchConditions that fail the installation if false, feature conditions set the level of the feature if true.
That means that you're setting the feature level to 0 during uninstall/repair/modify.
That in turn, causes the feature to be ignored during the operation which is why it isn't removed.

Feature levels are intended for default selection of features to install.
To get the feature to uninstall, remove the Condition element altogether.
