I think you have mischaracterized the argument. George is, essentially, saying that, based on his FACTS, K will not be a stand alone drug and the other side is saying that the evidence suggest that K could be both stand alone and combo.
K will be a multi billion dollar COMBO drug stated by some while the other side says K will be a multi billion dollar STAND ALONE drug.
There are more than 100 different cancers with p53 issues so I don't know how anyone can state absolutely and with any degree of certainty that K will not eradicate one or more of these cancers. There are certainly no FACTS that suggest this because K has not been studied against the vast majority of these 100 cancers.
I do, however, agree with your bottom line:
Either way it will benefit many in need of help and also set many families financially.
