I'm not the original recipient of this question, and I'm a new user, so feel free to ignore me if you'd like - but the short answer to this question is that the bare facts presented at trial are consistent with an accidental poisoning rather than a deliberate one.
I'd really like someone to sit me down and explain how it is possible to get to the level of certainty required by a guilty verdict in this case, without resorting to speculation or misrepresenting the evidence. Speculation is definitely an interesting exercise, as is bringing in evidence from outside the trial (eg Simon's allegations of previous illnesses), but I'm far more interested in how a juror could get to beyond reasonable doubt here. As someone who followed every day of the trial closely, I just can't get past how weak the prosecution case was.
To take just one example, the prosecution alleged Erin accessed iNaturalist posts about death cap sightings and then immediately travelled to those locations to harvest them. But no evidence was ever presented to show this, it was just pure speculation. The prosecution showed nothing from Erin's devices to show she saw the posts in question, and the evidence from Matthew Sorrell about the cellphone towers only proved Erin's phone connected to certain towers, not that she travelled to specific locations. A juror could fill in the gaps here to find whatever narrative they want, but they wouldn't be using actual evidence to do so.
