First, "anyone can compile it itself" true but only if you don't mind to install a linux distro just for that, and also you have a modern pc with at least 16gb of ram, a decent cpu, 500gb free space and a full free day dedicated to it. Also the process it's a pain in the ass, it's not difficult but tedious as hell.
Secondly, nobody are requesting a full complete and polished build, just a test build to check how pie it's working and progressing. This is a scene forum, where people come to "play with their hardware" so they know what to expect about a software that still in development.
And finally, I can understand that developers don't want to compile an oficial test build because they prefer to launch a complete and tested version, it's their decision and this is fine, but there are people here that compiled a test build but "if you wanna test it do it yourself" stuff because potato, so yep snob people.
