it's really is not the same at all

Redhead limits third party distribution

Google _sells_ third party distribution but forbids the third party to also provide products of a 4th party.

Both can be legally and ethically be discussed.

But one is open source being less open then it should be.

But the other "(effectively) forbids selling of a product of another vendor in context of duopoly".

That the product is based on a open source from the 1st party is overall irrelevant here.

I.e. this isn't really about open source, this is about _very_ fundamental rules of (proper working) capitalism being breached in ways which iff widely tolerated are very likely to lead to economical & innovation decline and long term collapse sooner or later.
