The FSF goes against the interests of companies like Amazon. For instance, they recommend AGPL for web services, big tech hates it, they will rather rewrite the thing from scratch under a permissive or proprietary license then use anything AGPL.

In fact, the trend is to move away from GNU. Clang over GCC, musl over glibc, uutils over coreutils, etc...

The FSF has an extremist position. Not only they promote free software, but they also don't want proprietary software to even be an option. For instance Debian is not up to their standards because they have optional repositories for nonfree software. I can't imagine Amazon supporting such an organization.
