> The UAE government owns majority holdings in telecom companies Etisalat and Du. This gives security services the power to observe all communications on their networks.

> The Arab state has also used the Israeli-developed software Pegasus which allows agents to listen into private calls and read messages, even if they are shared on encrypted apps like WhatsApp,.

This seems to be the key part from a tech standpoint. Notice that it doesn't come out and say whether Pegasus played a part in this particular arrest, or the telecoms, or both, but it seems to be implied.

Also, I'm intrigued by the punctuation error at the end: "...like WhatsApp,." Did an earlier draft go on to list others? Does Pegasus help governments read messages from Telegram? Signal? It would be interesting to know more.
