Because there are not that many linux users using 32 bits systems. So far, nobody complained so our linux binaries builder never bothered about it. I will ask him if he wants to build 32 bit binaries.
Really ? Writing on a 32 bit Lubuntu here.
IMHO a major (really
major) use case for Linux is to have a perfectly modern operating system that runs well on old hardware (thus 32 bit), since MS and presumably Apple as well leave this field completely open. They have interest in increasing system requirements of operating systems and applications over the years so that consumers are forced to buy new hardware, just because the old hardware no longer fits the requirements, and not because it's broken. Win 10 needing 2 GB RAM is insulting.
Try viewing modern internet sites with hardware from the 90s. All of these high-resolution and huge images everywhere, it's a pain.
