That's completely false.But it still stands that those who stand on original canon would, logically, need to reject the updates and retcons in Lands of Intrigue as much as they reject amethyst dragons for the PDKs or Sammaster coming back from the dead.
It's like claiming anyone who hates burgers from McDonalds hates burgers in general.
The objection to the retcons is that they're bad, not that they happened at all.
The Purple Dragon Knights becoming a Realms-spanning organization of multiverse-watchers using child soldiers, the addition of the Aevendrow, etc. are bad changes.
The Tiefling lore from Brimstone Angels was absolutely fantastic and fully justified the retcons necessary for it.
