I can't speak for others, but I care about binary size as a user because it tends to be a reliable signal of overall software quality (though there are definitely exceptions). I also find it incredibly frustrating when an application I rarely use fails to launch because it wants to force me to download, process and install massive updates for features that I don't even want. As an engineer, I care about binary size because gigantic binaries tend to require far more time to compile, move around and work with. Gigantic binaries tend to be a reliable signal of slow, toxic, internal processes that chew up positive energy and produce cynicism and frustration in it's place. It's not about the disk space per se, it's about treating waste as if it's a virtue.
