Maybe I just wasn't paying attention at the time, but I don't recall seeing comp finish complaints/rants here. I was under the impression those came more in the form of complaints to the shop, probably combined with requests to have the finish prettied up.
The caveat to this is that the original competition finish, or competition grade, or whatever is was called at the time, didn't have the decarb removed and quickly acquired a coat of surface rust. I don't know that I'd call the discussions here about that complaints/rants, but there were certainly discussions and expressions of surprise that normally corrosion-resistant INFI rusted so easily. But after that was replaced with the new type of comp. finish, I don't recall seeing even "complaints" of that sort here.
But then again, there were a few years when I wasn't paying much attention, so my observations might not be worth much.
And a further disclaimer-- I ordered a couple of those original comp finish knives that rusted just sitting in a drawer, and I wasn't expecting that. However, since they were offered as straight out of the oven without any finishing other than a really sharp convex edge, I didn't think there was anything to complain about. I was curious though, and learned all about decarb on this forum. When I found out that TGLBs could be special ordered with comp finish, I was hesitant at first, but after learning the new competition finish had the decarb removed, I ordered the Daryl Dixon combo (Competition Finish with Tan and Black G10) and couldn't be happier with it. When I ordered my Butaniku, I asked for Competition Finish, but was told that they weren't doing it anymore and it couldn't even be special ordered. Even if I promised not to complain that it wasn't pretty enough.
When they finally get around to bring Baby Butaniku's back, I want mine in comp finish (if I can't have satin). I hope no one gives them cause to quit offering it before I get mine.
