Can someone explain why GDKP is so hated?

Here’s what they actually said:

Nowhere in that post is anything stated as a certainty on the relationship between RMT and GDKP and as a matter of fact they called it experimental, which implies they were uncertain what the outcome would be.

Edit:

Corrected by Zipzo they do mention there being an undeniable connection between RMT and GDKP.
