It's removed from Elsevier's site, but still available on PubMed Central: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11026926/#
The worse part is, if I recall correctly, articles are stored in PubMed Central if they received public funding (to ensure public access), which means that this rubbish was paid with public funds.
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.
