When I was reading about Internet censorship in Iran and what they have done in recent years, it made me think of WhatsApp.<p>They have blocked most of the popular messaging platforms including Telegram long time ago but for some reason they have not blocked WhatsApp.<p>Since the current round of protests in Iran started in mid-September, they also blocked WhatsApp, but only because they don't want people organizing, discussing and sharing in groups. Basically everything is blocked now and this new development is most likely a temporary thing until they can handle the protests.<p>But isn't the fact that they haven't blocked WhatsApp in these years suspicious? Maybe they have access to NSO's Pegasus spyware or something similar. I don't think NSO would sell it to Iran considering NSO is an Israeli company, but they could still do it by using a middleman and not letting NSO know who the real customer is. Or maybe they developed a similar tool themselves because they have the motivation and the money to buy the information even if they are not capable to find it themselves.
