It’s a liability for them. They’re a small project and someone who just hates open source community projects can sue them out of existence for non-compliance.
That may be a rationale, but then they act to help governments spy on people. This is a no go. I understand that the government created that problem, but they should just refuse acting as proxy-sniffer for governments here. Who in his or her sane mind would want age-spying daemons to run on their systems? Next thing the BSDs will do is to support systemd ... then we can integrate the sniffing and call it systemd-kiddie-protector.c.
