I may read the article at a later time, but the pic you posted does not claim 6 million jews were incinerated, just that there was a build up of oven construction, and the reasons for it being in dispute..... I'm open minded and definitely not defending a narrative, just asking you to show me the claim that the mainstream narrative claims 6 million were incinerated, as to the apparently not mainstream narrative that I was taught in the 80's that 6 million were killed, and disposed of in various ways, including an industrial attempt at incineration.
