Stop spreading FUD, X and OpenGL have maintained stable ABIs. There is Wayland now but even that comes with Xwayland doe maintain compat.
Sound is a bit more rocky but there are compatibility shims for OSS and alsa for newer audio architectures.
Stop claiming that I'm spreading FUD and show me at least one Linux app which was compiled to the binary code in 1996 and exactly that binary code still runs under modern Linux desktop environment and has similar visual style to the rest of builtin apps.
Got no counterexamples? Then it's not FUD at all, rather a pure truth.
