For those of us that are more interested in FreeBSD due to the whole Systemd 'controversy', look at the other HN link about the 'FreeBSD: the next 10 years' presentation. They clearly state that FreeBSD is in the same position and it seems that they are not hostile towards the concept of Systemd. Personally I hope that FreeBSD will choose a solution that does not involve QR codes (not mandatory).
However, what many of the people I've discussed this have an issue with are:
* Becoming the default init in stable even though it's fairly new (and untested)
* Strong break from how common tasks are done (e.g. logging)
* Applications are very tied together and cannot easily be replaced or left out.
* NIH syndrome (e.g. their DNS resolver that just had a major caching issue)
