I actually found the parent to be informative, flamebait, but informative. The later response was even more flamebait-ish, but still had some interesting information (the existence of a securelevel LSM at one point).
I, at least, did not know about either securelevel or its short-lived appearance in the Linux kernel.
Perhaps the parent was trolling, but I don't think *this* particular post shows a major decline in the discourse here. YMMV.
