There's tons of software being released that still supports Windows XP.
Probably more by accident than anything else. When XP was released, Apple was still using IBM (not Intel) chips in their hardware and they in turn still supported Macintosh OS 9 (and probably 8). In fact, Apple was still releasing new updates for OS 9 at that point. Sublime doesn't run on MS-DOS either.
Frankly, if you're using XP, you really shouldn't expect anything (including software, hardware, the operating system itself) to work well, if at all. And if you're using XP connected to the internet, you should expect that your machine is spending most of its time mining cryptocurrency or DDoSing random targets, because I guarantee it's infected.
