I find it rather strange that someone should give their company a name that is so similar to one that operates in a number of different countries. This could lead to ambiguity particularly by the general public (for what it might be worth).
It was amusing to read in the news report that 'Arrival, which now employs more than 1,400 people, was founded in secret in 2014 by Denis Sverdlov, a Russian telecoms entrepreneur'.
Maybe he just hadn't heard of Arriva.
