For the moment, the path checked for SystemD is /usr/lib/systemd/system.
I installed ddos-deflate on 4 different installations, this path existed only on one.
It looks like more frequent to use /lib/systemd/system for SystemD services.
That why I propose this pull request to modify install.sh and uninstall.sh to use /lib/systemd/system instead of /usr/lib/systemd/system.
