@RL_Dane @drewdevault Maybe one very recent example of relevance: systemd added now example code how to use systemd notify w/o using sd_notify by including example code as MIT-0 in the docs.
They discouraged linking to libsystemd for things like sd_notify before, too, but that way they want to actively encourage everyone to simply use UNIX sockets directly.
This is, to me, a great example of using a very permissive license.
