Yes our nadir/jalu last aka schnuller is very good at getting on peoples' nerves, he sometimes (yes, not always) even does it on purpose.
But you are failing to read between the lines and you are now stuck looking at the finger that points to the moon.
Nadir is trying to give voice, admittedly in a kinda fucked up way, to a series of preoccupations that go far beyond the putative elitism often associated with old school *nixers and debianists.
We may not like the way he is telling it and we may disagree on the fact it is a real issue, but it is undeniable that the level of questions and answers you read on the various channels of our "linux" world is on a free fall.
He's not talking "in the last months", not even the last few years and it certainly isn't because of systemd (although it is easily the proverbial last straw).
The decline happened slowly but steadily in the last decade at least, and was inevitable with the increased use of the various linux based systems.
Some (well, quite a few good ones actually) are genuinely concerned that what they lived as a great passion about something, is gonna get lost in a race to clock beans as a measure of greatness.
Many have lost interest in sharing with us what they know exactly because of this. Not all those who know stuff have gone away, but we're definitely shorthanded, and it is not by covering the umpteenth "how to install the real firefox" or "I am stuck with a black screen after upgrade" threads that this is still a place of learning.
Nadir is simply trying to call the community up on the fact that we're no longer learning stuff, we're mostly just patting each others' backs for being users of one distro.
Could he have been less assholish about it?
Of course, but he's who he is and even in the face of how he acts, to put him in the troll category is just shortsighted.
Now, can you go beyond that?
Bye
