But in any case, this is false dichotomy, and likely exaggerated one to begin with.

The tools in question in OP should be easy to build from source and not rely on the host's architecture, to be usable on platforms like ARM and RISCV. It's clear that in the android ecosystem, people don't care, so F-Droid can't do miracles (the java/gradle ecosystem is just really bad at this), but this would not happen if the build tools had proper build recipes themselves.
