We've asked Uber for comment. Its service continues to operate in Turkey as of this writing, although there's a court hearing on Uber scheduled for June 4th. Critics aren't entirely convinced there will be a shutdown, though -- one Uber operator speaking to Bloomberg called an anti-Uber crackdown an "election pledge" that didn't carry much weight.

If there is a ban, it would compound Uber's ongoing problems finding acceptance abroad. It recently dodged bans in places like the Czech Republic and Egypt, but it hasn't always been lucky -- just look at London as an example. In Turkey's case, it's facing both the usual opposition from taxi drivers as well as a nationalistic government bent on protecting local businesses.
