I suspect the Internet blackout in Iran is not actually related to its citizens - it isn't about silencing its citizens.
It is to prevent hacking and tracking by US and Israel of what is going on over there, it is defensive since it has been shown that Iran's connected infrastructure is thoroughly compromised.
The blackout started back in January before the US even got involved.
Due to widespread protests and an attempt to crack down on coordination. This chain of events was widely reported.

The internet is only off for those who don't have a special sim card, i.e. those who aren't associated with the IRGC.
Is Iran's domestic internet still fully operational (sans access to/from the outside world)? If so, I wouldn't think the cut-off would help much security-wise because a single Starlink terminal would allow the US/Israel domestic access.
How do people communicate now? And why wouldn’t that be compromised?
It’s defensive indeed! It’s defense against the people whom the regime is most afraid of!
Except that Iran has been doing it since 2019: https://en.wikipedia.org/wiki/Internet_censorship_in_Iran
Don’t know why you’re getting downvoted for pointing out the obvious: yes obviously the US and Israel will exploit the information system of their enemy if they can, and it’s absolutely rational to deny them the opportunity to do so.
It’s 100% to prevent citizens from becoming organized. The regime is most fearful of this.
