Yes you're right, communication from within Iran has been almost exclusively formal, with the occasional journalist that tends to interview anonymous subjects quite naively and almost always with a heavy bias.

Unfortunately it's difficult to keep up with their discourse if you're not immersed in the culture. Iran is a bit of an island, and unless you're physically within the country I think it's pretty much impossible to keep up to date with everything even if you read the news, watch TV all day and read Whatsapp/Telegram all night.

I'd love to see communication restrictions and internal repression loosen up a bit. Information warfare has been a huge factor for Iran over the past 20 years so I can see the desire to guard against that (especially in this last war when they basically physically pulled the plug on the internet because the communication infrastructure was compromised and was being used to stage military strikes and disable the electrical grid). But ultimately I think those restrictions backfired over time, causing confusion, misunderstandings and security holes as people found ways to circumvent the restrictions anyway (as they tend to do). Repression is seldom the answer.
