Let's try to explain this without your neoliberal/communist bollocks.
FOSS software is licensed by those who write it under some form of licence (there's more than one, almost certainly more than one will be used by various components of a distro) which enables copying. This is not an accident, it's by design. In case you missed that let me repeat it: this is not an accident, it's by design. If you have comprehension difficulties feel free to read that until you understand it.
That has several consequences.
Firstly the material that Red Hat/IBM construct into RHEL will have come from multiple sources. Although they're a major contributor to Linux and to the many other pieces of software in a distro they're only one. Other people's contributions are used. And remember this is not an accident or mistake on the part of those other contributors, they intended this to happen. Also other distro maintainers also pick from the same smorgasbord of FOSS S/W to construct their offerings.
Secondly, Red Hat/IBM offer the source of RHEL for redistribution. They have to - it was the terms on which they themselves used it which require this.
Now if there's anything which you might possibly regard as cummunistic in this it's the offering of work on those terms. You have to shift "communists" not to those "wanting a free ride" but to those providing the "hard graft".
TL;DR You have at arse about face.
