Doing so cemented Uber's presence in Russia, and several satellite states, without having to compete hard in a tricky jurisdiction.
I would not bet on that. Even after the merger, Uber-Yandex is only the second online taxi booking service in Russia by the number of rides. The first spot belongs to the recently merged RuTaxi-Fasten group. Of course, with this being Russia, RuTaxi and Fasten "forgot" to ask the permission of the anti-monopoly regulators and tied to keep the merger secret. As the result, they now face a full-scale illegal monopoly investigation.
It is refreshing to see Uber playing by the rules when their competitors do not; there may still be hope for them.
