Okay, so we can clearly see that the original patterns and all the pattern data is still preserved in the module. But if you were going to play those patterns one after another, you will quickly notice that they will sound completely butchered and it actually requires a lot of work (and knowing what the original module sounded like) to get these to sound "as intended" again. Please don't assume malice here but rather assume that the artist was too lazy (or unknowledgeable) to clean up the module and remove all the original unused data. There are dozens of similar tunes on ModArchive (both recent and ancient) where people forget to remove unused patterns and samples after they started off their tune by taking someone else's module and adding new patterns to it.
Whether this was done with or without permission you cannot really tell but knowing h0ffman personally, I'm pretty sure he would not mind at all about this module. Sure, his original patterns are still buried somewhere deep in there, but it requires a bit of knowledge to find them, and I think that if you have this knowledge, you are also one of those persons who know that people often take other modules and start a new song from scratch "on top" of those modules, and that those butchered patterns are the result of it. Let's be honest, h0ffman's track is much higher quality than this module, and I think it would be easy to recognize for anyone finding those "hidden" patterns that they were made by a much more skilled person than those that are actually playing in the order list.
In addition, you will find that the artist did not add any personalized sample text at all - some of the samples even still refer to h0ffman's original sample texts. This would be an entirely different issue if the artist claimed in the sample text that all samples and patterns are their own - but they do not do that, which again I would classify as laziness rather than malice. I'm totally on your side that people should remove the original patterns and add proper credits to their module (I am sometimes this close to rejecting a module because it's ten times the requires size due to containing huge amounts of unused data); but I really don't think that we would get anywhere by driving people away for these mistakes and calling them out for plagiarism. A more positive and an encouraging comment to leave on this module would be something like "Next time, please remove all unused samples and patterns and give credits to who you took your samples from."
