The bug
The "Download" link on https://minecraft.net used to open the download page (https://minecraft.net/en-us/download/) where you can download the server and the launcher.
Since some weeks it loads https://minecraft.net/en-us/store/minecraft/?ref=m which is pretty annoying, because if you want to buy the game you would have clicked "Store". Additionally https://minecraft.net/en-us/download/ can be accessed without being logged in.
This makes it only harder to naviagte on the site and you have to rely on search engines to find the page you want.

Edit: You can find the page under "TRIAL & DOWNLOAD" in the menu
