My interpretation, stemming from his statement that it is a problem to brick machines and his statement that some programs need write access, is that something needs to be put in place, but we can't unilaterally restrict root (which would be very un-Unixy to do). I think he was fairly ambigous in details on how to fix it (possibly because he wasn't sure the best path to take), and included with some fairly blanket statements about policy/belief that allowed people to interpret his statements however they were inclined. Unfortunately due to the polarizing effect of systemd (and Lennart's prior projects, and possibly Lennart himself), there are plenty of people inclined to believe he doesn't care.
