This is true. If you're a paying member you get it under what they call the "Reciprocal Community License": https://opcfoundation.org/license/rcl/1.00/opc-reciprocal-community-license-1.00.pdf

I think each of the stacks are maintained by a different company under contract. I don't think they treat them with different priorities, though the initial proof of concept stack was the C# one. Still, these are just stacks, not SDKs, and they will probably never be more than that.

One key difference is that Eclipse Milo uses the Eclipse Public License and
Eclipse Distribution License (BSD).  If I understand correctly, the OPC
Foundation implementation are GPL license.   This makes Eclipse Milo a lot
easier to distribute in commercial projects.

AFAIK as paying member of the OPC UA group you get a commercial license
allowing you to use the stack without forcing you to publish your source.

Also AFAIK the java-based stack is not the primary one, so new implementations
will first take place in the C-based one and later be ported to Java.
