GCC was implemented in C and there are plenty of other C compilers written in C. GCC has been converted to C++ at some point, but large parts are still essentially C and I do not think the change to C++ was actually helpful (but others may disagree). In any case, the idea that one needs C++ to have C compilers is certainly simply wrong.
Clang/LLVM with its more permissive licence sees _much_ wider use and is written purely in C++. PlayStation, automotive, platforms and runtimes like Chromium/V8, Android, etc. are all built with Clang.
Naturally GCC was originally written in C, given its age, and the original GNU coding standards document.
With time, the GCC developers acknowledged the benefits of using C++ over C, and migrated the code.
GCC requires a C++ compiler to bootstrap since around 2012, and GNU coding standards has been updated to several languages beyond C, time to go up with times.

My original C compiler was implemented in C and then bootstrapped. Zortech C++ was implemented in Zortech C, and then bootstrapped.
D was implemented in "C with Classes" and then translated to D and bootstrapped. There isn't a line of C code in it.
Over time, we gradually replace the C-isms and C++isms and anachronisms in it to native D-isms.
Clang/LLVM with its more permissive licence sees _much_ wider use and is written purely in C++. PlayStation, automotive, platforms and runtimes like Chromium/V8, Android, etc. are all built with Clang.
Clang usage is a fraction of GCC usage.

How is this relevant? (also wider use for C I would doubt)

I think the fallacy of this argument is obvious.
