That's a very disingenuous argument and you know it. Starlink is under SpaceX. Do you also think that is wrong then too? They are effectively doing the same kind of thing.
Kuiper is not under Blue Origin, and there are no whispers of Amazon and BO merging. You're the one being disingenuous in suggesting that companies have to be merged to buy services from - or cooperate with - each other.
Being combative and wrong would be an unfortunate combination. Combative, wrong and ignoring counterexamples that disprove your assertions and hurling ad hominems puts you firmly in troll territory. Good day.
FWIW, SpaceX launched a Tesla roadster into space without first having to merge with Tesla.
