From this article on vice.com:
The self-proclaimed Islamic State (IS) has severely restricted use of the internet in its de-facto capital of Raqqa, requiring that all residents — including those in the militant group's ranks — access the web from observed internet cafes, according to international monitoring organizations.
An IS leaflet photographed and circulated by the Syrian Observatory for Human Rights and the activist group Raqqa is Being Slaughtered Silently (RBSS), advises that "all owners of shops with satellite internet must comply with the following: Removing Wi-Fi boosters in internet cafés as well as private wireless adaptors, even for soldiers of the Islamic State."
...
Activists worry that internet restriction is intended to clamp down on citizen journalists, human rights workers, and potential IS defectors.
Even under IS rule, activists have managed to sneak out videos, images, and accounts of daily life. In September, a woman with a camera hidden in her niqab walked through the city narrating her experience. The smuggled footage was aired on French TV.

Actually, this IS development does represent a step down from the Syrian norm. When I travelled around Syria in 2008-2009 before the civil war, sure, it was a police state to a large degee, but people could still browse the web anonymously. When you went into literally any netcafe, you could ask the proprietor "What's the proxy?" The first time, he would say he didn't know what you were talking about, but if you just asked again, he'd immediately drop the pretence and show you how to enable Tor or some similar way of getting around the country's filtering and surveillance. Also, there were a large number of open wifi hotspots in Latakia, Aleppo and Damascus.
