This splitting of hairs between the legal entities and the work of their paid teams/employees isn’t adding strength to your argument. Companies are run by people and those people get to make decisions on the allocation of resources. If they decided to put substantial resources into OSS, the company does get to claim credit there.

Great! Maybe the Ruby community can strive for this in the future but it does not reflect the OPs point that these companies and their outsized contributions via time and money are still core to the existing community we have today.
