alt Hacker NewsThis is only ever relevant for proprietary software. Free software does not require a stable ABI. Great that wine exists but it should be useless.
(That and Linux doesn't implement win32 and wine doesn't exclusively run on Linux.)

Free software can still benefit from a stable ABI. If I want to run the software, it's better to download it in a format my CPU can understand, rather than download source, figure out the dependencies, wait for compiling (let's say it's a large project like Firefox or Chromium that takes hours to compile), and so on.
We exist in a world where proprietary software exists, and always will exist. I want to be able to run said software if it's the best tool for the job, not be hobbled by an idealistic stance of "all software should be free so we don't bother to support proprietary software".
Stable interfaces and not being in versioning hell (cough libc) would actually be good for FOSS as well.
If you make a piece of software today and want to package it for Linux its an absolute mess. I mean, look at flatpack or docker, a common solution for this is to ship your own userspace, thats just insane.
