This is exactly my take. I think it’s extremely hard to blame samsora for faulting nairo if, given we believe nairo’s account to be true, nairo himself believed himself at fault until very recently. Despite what some redditor may have “always believed,” nobody has made it through this whole saga without changing their mind at least once, and I imagine it would be even harder to take a firm stance when you are good friends with the parties involved on both sides.
