It's also slightly grounded in facts, but in fuzzy, outdated "facts" that were disproven later on in a way that made the trope impossible.For the record this idea of cloning clones and deteriorating over time is actually a fairly common sci-fi trope and the central plot point of the amazing game series "destroy all humans"
Basically, blame what went wrong with Dolly the Lamb. That's where the idea started, but it was later proven that Dolly went wrong was messy epigenetic and telomere problems caused by the style of cloning. More modern forms of cloning don't have those issues, so the "clones of clones" problem comes up as the problems of aesexual reproduction: Extremely slow mutation. Any disease works on the whole species.
Of course, we have no clue which one of the half-dozen or so forms of cloning that are known currently the Grineer use, and they might well be using a form of cloning that hasn't been invented yet. And the "cloning degeneration" might actually be a persistent plague or set of diseases that everyone is affected by in some way, but the Grineer don't have the genetic diversity to keep it from ruining them.
