FWIW, Henry Scherer does first class work. I'm not a Contax camera fan, so can't speak to that. However, when I was looking for a technician to refurb one of my Zeiss Contax CY mount lenses, I contacted Zeiss directly and they referred me to Henry. I have refurbished a number of these lenses through him, and been very pleased. The lenses come back in first class shape and perform "like new", and as good on a Sony A7RII as any new Loxia lens. My experience confirms (small size sample and prone to cautious generalization) my suspicion that those who compare new digital lenses to old glass and find in favor solely of the new are simply comparing fresh with old and tired. Make the comparison fair by "refreshing" the old, and the old gives the new more than a run for it's much less money. I have run both the Loxia and Contax CY lenses side by side and the old performs fabulously. The new Loxia's are good and I like them, but Henry sure knows his business, and I'd recommend him highly. Does he love is Contax cameras and grind his teeth over the posers who ruin them? Sure. And maybe(?) that comes out in the article? Not a surprise. But despite the naysayers, Henry really does know his business. Searching through the Roger Hicks piece, he seems to echo much of Henry Scherer's comments.
When I began 2017 by following Zeiss ZM lenses towards a Leica, I asked Henry about ZM glass. He doesn't work on them and knows nothing of Leica or Leica service folks that he'll pass along. Commenters on the text from his website are errant in conveying that he's speaking about Leica and the folks we know who work on them. He's talking about the ebay posers who cobble cameras that look good enough for a photo but could never work. The full text makes that rather clear.
FWIW, I've recently been looking into getting a Nikon F2 to run my now refurbished Contax CY mount lenses with an adapter as a film option to free me from dependence on the Sony A7RII for certain functions. If you look at an option like this, you'll begin to wonder about CLA for an old Nikon, and a quick search turned up these guys:

Looks like a real operation, too, and for a wider range of cameras. Their prices look a little lean to me compared to Youxin and Scherer, so I would want to get more information, but it's a place to start. FWIW, I have a "new to me" Leica M4-2 on it's way back to me from Youxin Ye, and have high confidence that having a camera checked out - if it's value warrants - will prove worth the money. Plenty of cameras won't merit the effort. Those are simpler to just buy another off ebay.
THere's not rock certainty that old tech won't have a fit some time. Even with a CLA / refurbish, something can still give out... the same way it does with your car: "because it's time". But if you're careful and prudent in whom you work with, seems like a good idea to me. But a good service provider is worth his fee. Pay him and don't argue. If you're going to resent it, or try to do it on the cheap, then don't do it at all and stick with new equipment.
