If Isar will get a large scale commitment from the government(s) to launch the OneWeb 2.0 constellation, as the European alternative to US, Chinese and Russian systems, they may well become a major launch provider. And of course they are already working on a much larger reusable rocket.

Although the original OneWeb satellites were assembled in the USA, they were developed in Europe and the components were always sourced predominantly from Europe, Canada, and Africa, with only some parts produced by the European companies in the USA, and even fewer parts sourced from the US companies. It is a very European satellite.
