We do. It's not very good. As in, there isn't even a properly functioning domestic search engine that can match the quality of anything past AltaVista. The only local platforms worth a damn are the ones you'd be using anyway. (the local equivalents to Uber, Maps etc.)

All other platforms (instant messengers, social media, news) are massively unpopular for being horrid to use at best, and government spyware at worst.

To slow down the immediate damage the government has rolled back a few of the recent restrictions, hence why I can access HN. Among Google and a handful of other basic websites. But they are obviously experimenting and trying to figure out how much censorship they can get away with. There is talk of a planned "whitelisting" of the country's internet. Where almost all but a few big important services are blocked completely. This would have the bonus effect of making circumvention using VPNs and other methods even more difficult than it already is.
