FYI the ones you named include ones priced exactly the same as Uber. Uber doesn't take the same cut in every country.
The competitors inDrive, Bolt, or Yango almost always beat Uber on price.
You're misinforming here, giving bold statements based on not spending enough time in some of these countries, not knowing the local market well enough.
In the above cases where the difference is about 0, both Uber and the other app are generally the cheapest ones on the market. There tend to be other slightly more upmarket apps that cost more but get you a nicer car/service. Cabify, IM. Waymo is moving into this. Obviously I'm not super familiar with every single market but clearly neither are you, and I know the above ones.
