Even @[email protected] gives it backlash despite being a moderator of Lemmy's biggest privacy community. A quote here: "grapheneOS trolls are downvoting every single post and comment of mine, and committing vote manipulation on Lemmy. They are using 5-6 accounts." That was in response to downvotes on a comment posted in the c/WorldNews community, which is entirely unrelated to technology.
It seems to me that you might be confusing things: You say that people hate the OS but share a comment complaining about the community of users/fans, not about the OS.
I have never used GrapheneOS and cannot comment on the OS, but I have seen some users in different communities commenting that GrapheneOS is the only valid alternative OS and discrediting any other OS. It becomes tiring pretty fast.
I'm going to paste here the comment I wrote on another post about this same issue:
Organic Maps and OsmAnd are not adding ads during navigation. Nor "promoted pins". Nor ads when browsing the map. Nor tracking your every move.
Seriously, give them a try. And remember that, if the maps are lacking information, you are free (and encouraged) to improve them on OpenStreetMap.
