All the while keeping a crontabbed eye on directory content, of which there should not be any. # You need root privileges to look for content after the chmod. If preventing writes breaks your KDE Plasma desktop, something is badly mis-engineered. If it still manages to write stuff to that directory, something "evil" is going on, in that the telemetry stuff is using elevated privileges, and it may be time to use nullfsvfs.
