Lineage and GrapheneOS are not even in similar levels here. Yes, LineageOS (or any of its commercial forks) is great I'd you have anything other than a Pixel phone. Definitely beats having any stock Android. But having the choice and telling people that "GrapheneOS is not the only option" without context is intentionally guiding people that could potentially have a much more secure and way more private mobile experience look somewhere else just "because".

I don't pretend to know what tour reasons are, could be because of Micay, could be because the GOS team of developers has no filter, I don't know. But even Louis Rossmann, who openly chose to get away from GOS because of Micay's actions has said, time and again, that nothing even comes close.
