As a member of an open source community involved in one or more blockchain projects, I can attest that many of these things literally are indeed free.

An open source community can do a lot and not everything.

I'm not aware of any opensource community being happy at doing on call.

Or end customer support.

Or even marketing.

And if we look at successful opensource projects, than we have companies behind them.
