Apk4free.net collected some old versions or legacy versions for SuperSU (eu.chainfire.supersu, A useful Tools app for Android). You could download one of the legacy or old version of it !
SuperSU is the Superuser access management tool of the future.
!!! SuperSU requires a rooted device !!!
SuperSU allows for advanced management of Superuser access rights for all the apps on your device that need root. SuperSU has been built from the ground up to counter a number of problems with other Superuser access management tools.
This is meant to replace Superuser (if installed), you use either one or the other. You cannot combine them. Statements that this breaks Superuser are therefore completely nonsensical.
