It looks like you have mixed up /dev/null and /dev/zero (as a Dutch learner, I can see how that would happen). /dev/null is always empty and would be copied as an empty file. This is the correct target for symlinks when you want to disable a systemd unit. /dev/zero is an infinite stream of binary zeroes and would result in the behaviour you saw.
