I think the main thing is that it's common for apps to bundle their dependencies. The default for Linux is to use the system libraries for everything - not just glibc but also things like zlib, libpng, etc. As a result you have to go to significant extra effort to make a portable binary app, e.g. linking against musl.
That's one of the attractions of Go, and to a lesser extent Rust; it's way less work than C to get a portable binary.
I think 90% of the problems I've encountered are due to glibc. They could easily fix all of them by adding a GCC flag that would allow you to compile against old glibc versions.
They'll never do that though because they are ideologically opposed to it.
