Not a bug.

You need to be able to authorize yourself when you download these releases.
This can be done using cookies, example: wget --load-cookies cookies.txt https://www.factorio.com/get-download/0.12.30/alpha/linux64

To get the cookies.txt file use --save-cookies with wget (refer to the manual or google), most browsers also allow you to save this file (mostly through extensions). You'll need to do this after logging in at factorio.com to get the correct cookies.

It's probably easier to download the releases using your browser instead of wget.

Actually, I got a 404 from the browser first, then tried poking it with wget. (Also, some of my computers don't have web browsers. I guess I could use links.)
