The post I referenced was the suitability of oil filters meeting Mercedes OEM specifications. Specifically:

I followed the thread referenced in this statement as well as similar threads and pose the question:
"Where are all the millions of Mercedes diesel engines that have been killed by the many many millions of Mahle filters used over the last couple decades!? It's a shame that after long debate and research here on the forum it wasn't found that packed cotton fiber filter used by the millions over many years caused any significant verifiable damage. How many forum members have actually had an engine damaged by filter material?
You'd think that, arguably some of the best engineering staff of again arguably, one of the oldest and most successful automotive manufactures the world has know, would be at least able to spec the single most commonly replaced maintenance part!"
I take it you don't have an answer to that question?
I'd suggest anybody with questions about suitability of OEM spec filters read the original thread is for no other reason than amusement. The "debate and research" in my opinion are illuminating, maybe more about the debaters and researchers than the actual factual suitability of one filter over another.
I'm of the opinion that if in fact "there are a select few filters that do not spill dirt and cotton waste into the engine" there would be considering the vast numbers of them dead MB diesel engine vehicles everywhere. There in fact is not. To the contrary in fact it is almost universally accepted the MB diesel lower ends are some of the longest lasting of all engine, and how that could be with dirt and cotton waste spilling into engines is improbable, no?
It makes you feel good to fool around with some different filters so be it but there is little evidence that in the real world you'll be driving much longer than the guy that buys a decent OEM brand that probably hundreds of millions of oil changes have used.
"If someone only wants to use Stock Oil Filters I am OK with that." I'm sure everyone will be relieved to hear that!

"I take it you don't have an answer to that question?"
I think I have some answer to the question but I think that the answer is unacceptable to you.
Actually, I have not criticized the waste Cotton Filing in the filters. In the past threads I criticized that the Filter companies did not know the performance of the bypass section of their Filters.
I do not see how you can have quality control without some sort of spec to go buy.
As far as engineering goes the only thing that is unusual about the 617.9** Oil Filter is that fact that it has a bypass filter built in to it.
If you cut open a 1930-1950s Oil Filter you would have a good chance of finding cotton Filter medial in them. So using that material makes is no engineering break through.
I do not know what to say about the millions of Cars argument.
Even with what you believe is the best Engineers it is clear that Mercedes is not a perfectly designed car.
2 examples my Volvo Diesel is 2 years older than my Mercedes. I never have to worry about my Vacuum Pump parts failing and falling into my Timing Chain. Because the VW Engineers decided to drve it off of the Camshaft with a nice thick cylindrical Steel pin.
And, then there is those Pot Metal Window Regulator Mounts in my rear Windows.
Concerning the Oil Filter issue my positon is that there is room for improvement. And, I have tried to make an improvement.
"It makes you feel good to fool around with some different filters so be it but there is little evidence that in the real world you'll be driving much longer than the guy that buys a decent OEM brand that probably hundreds of millions of oil changes have used."
As for the above quote there is evidence that low micron bypass Oil Filtration (I modified the bypass section of my Oil Filter) does indeed reduce Engine wear and keeps vehicles on the road longer.
And, yes finding a creative solution to a problem has a "fun" element to it.
