It basically boils down to Uber considering themselves a tech company while Colombian law sees them as a transportation company that must obtain licenses and oblige to regulations around ride fees and such.
We will see. To me what Uber is currently doing smells a bit like a PR stunt. Especially with all the appeal to emotion in their communication to the users and trying to get them riled up on social media.
"Así lo cree Nicolás Alviar, el abogado representante del icónico caso contra Uber ante la Super Intendencia de Industria y Comercio, que en primera instancia ordenó el cese de operaciones de la aplicación de movilidad compartida en Colombia."
Either that says the Super Intendencia ordered the service shut down, or it says that Alviar (the lawyer playing offense) caused it to happen.
