I'm a full-stack developer that has used various build tools, including Maven, Gradle, and NPM/yarn. For our C projects, I also investigated CMake and Ninja, but they seemed more difficult to learn and more tedious to work with. GNU Make is a single binary that can be easily …
A lot of existing projects we had been running are based on GNU Make, it does not make sense to move away from that. To build on top of those, GNU Make had been used. A lot of experienced engineers in the team are already familiar with the GNU Make syntax and structure and no …
GNU Make is a great tool for simple builds where language-specific options are not available, or to provide shortcuts for common commands (e.g., "make build" as shorthand for "go build ..." with a bunch of flags). However, it is complementary to other build systems. It does not replace them, which is perhaps one of its greatest strengths as well (works with existing ecosystem instead of trying to do everything). GMU Make it simple to get started with, and the philosophy of understanding how sources map to outputs, as well as the dependency graph, are beneficial.
In general, it is fair to say the support is sufficient although we do not deal with support directly. There are a lot of forum people chiming in with suggestions or recommendations of particular usage or issues we run into. Since it is open software, patch and fixes will be available from time to time. A lot of information is available in the web now for knowing GNU Make from learning, example, teaching, etc.

For our C projects, I also investigated CMake and Ninja, but they seemed more difficult to learn and more tedious to work with. GNU Make is a single binary that can be easily downloaded, even for Windows under MingW32, is straightforward to learn, and works pretty well despite its age.
