I had never posted there before and if I was banned before I wouldn't be able to press on Create Post. I checked but have never received a message before from r/bangladesh that I was banned. I think they have an automatic filter that picked up on the words 'US sponsored coup'. Can someone post the same picture as me with the same text to see if this is not just a me thing? I checked, I can create comments in other subreddits but can't post comments or posts in r/bangladesh anymore even though I didn't receive a notification I'm banned. I can't even see the list of moderators of r/bangladesh anymore.
But another reminder the Reddit is a US website with links to their government and a lot of national subreddits are compromised like r/afghanistan
To answer your original question, there is a recent Vijay Prashad interview about this topic. No link cuz phone.
He says that the priests erupted because of genuine reasons. However, after the ousting of Hasina, discussions between various groups including the student group took place at the US embassy. This indicates that US is opportunistically taking advantage of the instability.
He said that the new president being a microloan preddling pro-US Nobel Peace Prize laureate could be a move to keep the military off their backs. But I think it's a bad sign signalling a lack of sovereignty.
