Edit: ah, it helps to read the press release properly, the research was done by by this company, so it makes sense that they're the primary source and that the marketing manager (and probably AI) wrote the article. I retract the accusation I've made below.
Digging into it further, googling "ötzi heddi abbad" I just find Dead Internet results leading back to this -- dare I say it -- hallucinated article. The image caption refers to "Augustin Ochsenreiter" but it seems he's just a general Ötzi researcher and his name is mentioned for the image credit.
This article from a German news service (I can trust this more than FamilyTreeDNA's marketing specialist) mentions that Ötzi has many relatives in Europe, but from the father's lineage: https://www.dw.com/de/viele-europ%C3%A4er-sind-mit-%C3%B6tzi...
If you go far enough back, I am also a relative of Otzi, through mitochondrial Eve. I can tell you this with absolute certainty without giving my DNA to some for-profit.
