What made you say so? Nobody here has implied there was. Yet...No one owns the languages but are just users. There is nothing to protect or defend.
Now that you mention though ... People have certainly tried to own languages sometimes successfully:
Back in the day Microsoft implemented Java for Windows and Java applets for Internet explorer. Sun Microsystems sued Microsoft over that. Which I suspect is why MS went on to implement their own ideas about a Java style VM based system, C# and .Net.
There is still an ongoing legal dispute between Oracle and Google over Google's use of Java. All of which is a reminder that we should not be using Java for anything. Not for any language feature reasons but to avoid any legal issues over ownership.
Many will point out the the instruction set architecture of a processor is the language by which software, i.e. programmers ultimately, talks to hardware, the processor. Well, you try shipping a hardware product that implements the ARM ISA language or the Intel ISA language. I think you will find Intel or ARM suing you soon enough, claiming ownership of their ISA language.
Which is why the world needs RISC V.
That sounds reasonable. Often it looks like bias.Just because someone says they like a feature of some language doesn't make them biased.
At the end of the day all programming languages are equivalent. They are all Turing complete, any problem that can be solved with one can be solved by all.
Of course high level languages are supposed to make creating solutions easier for humans. To that end the majority of modern HL's are on an fairly equal footing. Although they differ in syntax and the semantic luxuries they afford.
So, we might conclude that there is no logical, technical reason to prefer one HL language over another. A competent programmer should be able to get the job done in most of the high level languages available. from modern BASIC to Haskell.
Why then do otherwise intelligent, rational, skilled software people get so heated in the defense of their preferred programming language? Why language wars all over the net?
Clearly a lot of this comes down to personal preferences. To what people are used to. To the approach they have to programming. Etc.
They are biased by their knowledge and past experiences to a large extent.
Then there are advantages and disadvantages to using this language or that depending on things that are not strictly part of the language definition:
Is there an implementation that even runs on the platform (hardware/OS) I'm using.
Are there implementations for many other platforms so that I can create cross-platform solutions?
Is there a stable standard for the language so that I can be confident of the future of my creations?
Does it have lots of libraries, modules, etc available so that I don't have to write stuff from scratch?
Do the implementations of the language available meet my performance requirements?
Is there a lot of excellent documentation, blogs, tutorials, books, other support out available? A big user community to help out?
These are all practical matters that heavily influence language selection. Despite not being much to do with the actual languages them selves.
