alt Hacker NewsThey don't like GPLv3. The other BSDs used similarly old versions until they moved to clang, but netbsd is pretty tied to the gnu toolchain and aims to be as portable as possible, so they kinda have to stick to gcc

This is not the reason. We created this branch in July 2025 (GCC 12.5 was released on 11 July, 2025) and spent a year stabilizing it. A new system compiler is considered far too much of a risky, incompatible change to backport. Especially since lots of C code no longer compiles with GCC 14+ without significant changes.
Each time we upgrade the system compiler, it requires extensive work to keep all of our supported architectures in working order, and adjust our code for compatibility.
wasn't that around gcc4 or something era? gcc12 is pretty new
But the licensing didn't change between gcc 12 and gcc 16, so that doesn't seem like a good explanation?
