You mean like absolutely every other tank that has seen combat in this conflict, including all of the much vaunted Western MBTs? Perhaps the Russians are indeed leery of that sort of bad publicity, but it's not like Armata wouldn't be in good company, right? Not that you could expect people to be sufficiently discerning as to recognize this fact.
It's also remarkable how articles to the effect of "Russia abandons Armata tank" (with or without a reason being cited...) crop up year after year after year with monotonous regularity, yet it's still here. Funnily enough, this particular piece even flatly contradicts its own click-bait title by stating point blank that "Despite this, Chemezov confirmed that the T-14 “Armata” remains part of the Russian Army’s arsenal.".
Maybe we all need to countenance that this tank is going to enter service, and probably even hit substantial numbers at some point down the road. And that perhaps the hysterically embroidered accounts of its various failings and delays are actually no more than the typical teething troubles encountered by virtually any major new weapons system...
