Thats covered in the comments. They likely removed the relevant notes from their caching server (primal reads notes from there, not relays), so their users werent able to see it. Then they were rebroadcat and now theyre available. Everything is visible now, but multiple people confirmed these notes wouldnt load specifically in primal

And I dont think it sounds a weird topic at all to censor if youre a shirtless Primal surfer bro dev thats easily susceptible to propaganda, and you think youre doing something good by making it to your users cant see this "dangerous information"
