There's not much to disagree on the odds. Trajectories are known, uncertainties too and therefore probabilities of collisions can be calculated. Any disagreement here is easy to reconcile, whose assumptions and methods are more accurate? The disagreement is on the importance of the odds. SpaceX might be OK with a 1:10000 (or whatever) chance of collision, the Europeans want it lower. The Europeans could in the future force the issue. Move, or we'll fine you and forbid you from launching off of European sites and ban EU companies from using SpaceX.
