Sure they are. For instance the GNU C dialect family is C, and so is
every vendor's dialect.

Only ISO C is ISO C. ISO C is C, and so are some other things.

The Bible says it's the word of God; that don't make it true.

C90 and C99 are C languages which continue to be defined and exist.

Moreover, every C++ dialect, current and historic, is also a C dialect!

The ISO practices don't dictate to the world what is a dialect of C.
They do *produce* dialects of C, undeniably.

They only produce; they do not destroy dialects of C.

It's very hard to destroy languages; civilization still hashaccess to
(and interest in) thousands-of-years-old languages.

But it's a fact that ISO cannot cancel anything in the world.  All they
can do is express the opinion that they consider a document, and what it
describes, to be obsolete, not to assert that it doesn't exist.
