If they could credibly threaten your infrastructure then it makes sense. If they have no real organized hacking capabilities then no. But the US has already attacked Iran through computers before with Stuxnet and is the world leader in software and networking knowledge so it does make perfect sense for Iran to disconnect its networks from outside.

You might also have to consider the propaganda campaigns the US could run against an Iranian population with web access. If the population isn't more discontent now than it already was, "secretly" replacing commercial ad placements on western websites with US propaganda when the requests come from Iranian sources could make them discontent or inflame them further, which is bad for the Iranian government.

To say these on HN of all places!

> consider the propaganda campaigns the US could run against an Iranian population with web access.

I’m amazed at people who have access to freely express their opinions online, prescribe that 90m people should not have the right to freely access information because they somehow can’t be trusted to not fall for propaganda. What a patronizing and self righteous take.

		Just because I can see things from the view of the current Iranian government doesn't mean I support them or their actions. And its not like the US does nothing to suppress foreign propaganda already, they just more often try to drown it out with our own. Hell we just recently were talking about banning tiktok because just shaping what user-made videos was considered too strong of an ability to push Chinese propaganda and influence US citizens. And yes, we already know large masses of people will readily fall for propaganda, just look at the US political landscape, look at the entire field of marketing which is just propaganda for profit. Everybody across the entire world is vulnerable to propaganda, marketing and propaganda didn't become less common going into the 21st century, it just got better and harder to identify.
