Well get this, I live in London and I love Uber and I would definitely miss Uber if they stopped operating here. So your statement is wrong. In fact, our general slack channel at work had a ton of people posting sad faces about this news. But yeah sure I guess you know what every Londoner thinks...
I ride with FreeNow in my city, just as I did with MyTaxi before. Same drivers, same app, same prices, just different colors (and slightly less favorable terms of employment, from what I've heard from the drivers during the time of transition).
Their race to the bottom was absolutely beneficial to consumers while it was going on. Smaller rivals have nowhere near the resources of Uber when competing with Grab.
We surely missed Uber when it left.
I saw few acquaintances trying Bolt (in London) and the main argument is the first rides are free, then the next rides are free too if you refer a friend.
