So. Homebrew is illegal now too, then?

EDIT: People seem to be misunderstanding this screenshot. This is me running a program installed by Brew and it being blocked by macOS Gatekeeper. You can see me executing it from the command line and you can see in the error message that Homebrew downloaded it. Although brew is in general working for me, this particular formula's app got blocked. After making the post I resolved the problem and do not need help.

@mcc You can still run un-signed software, you just need to take an extra step of going to the security options and telling it to allow the launch of the program it blocked.

Plus, homebrew still exists, still lets you install and run things from the commandline.
