I'm pretty sure the "country restrictions" are about ITAR, not the destination country regulation.
When the page says "uh… do not use this to build a phased array radar… even though you could. And if you do, then in no way were we involved. Just don't", this is extremely likely to be about ITAR.
> License: Amateur Radio (Technician+) to operate, country restrictions apply.
This implies it's about operating a radio transmitter.
Iran will absolutely frown on that right now, as they've frowned on Starlink. Their internet shutoff indicates "empowering the public to connect across the world" is not really what they want.
