The plagiarism of copycat82 attempts to merge multiple prior art sources, but it is worse than trivial, stuck only as the least-usable subset of (each of) them, or worse: The self-contradictions lurk in copycat82, and nothing warns about them.
Even when copycat82 admits grave problems (with a single sentence, or two), it does not solve them. As such, it is also a self-contradiction, i.e: why it is published that way, as it is not verifiable without those needed extras, which copycat82 does not contain.
