For instance, could SpaceX refuse to carry OneWeb satellites because it is a competitor to StarLink.

Obviously SpaceX shouild be able refuse payloads as incompatible with their vehicle.

The obvious sources of the imposition of common carrier conditions would be the regulator, the FAA, and NASA who provide the launch sites and support facilities.

    $\begingroup$ deliberate duplicate of the 4 hour old question If OneWeb asked SpaceX to launch their satellites would SpaceX be able to say no? is probably not the best way to use Stack Exchange. Better behavior includes leaving helpful comments, offering to make a helpful edit (which can be rolled back) or even in some cases to go ahead and make a helpful edit. It sounds like you have some thoughts on the topic, why not leave an answer there instead? $\endgroup$

  • $\begingroup$ I think this is the interesting question at it's core, but short of editing it into this form I don't think it is salvagable, and that would be too severe an edit for me to consider making to someone else's question. $\endgroup$

  • $\begingroup$ You are trying to circumvent Stack Exchange's voting process and unilaterally have your own way by insta-duping my question. A single user never gets to decide what is "salvageable" unless its the OP themselves. SE rules apply to everyone equally. $\endgroup$
