And they even hide it from you by prefixing it with @, which is downright evil. So you never notice unless you look at the Makefile. Currently, that script clones another common repo using the unverified git:// protocol (because, why use submodules if you can do it in an insecure way?), but obviously, that can change any minute and could change just for certain IPs etc.

The potential for backdoors is extremely high and I think nobody should be using any software written by this developer / these developer(s), as they clearly demonstrated that they couldn't care less about your security.

I guess this is because gnupg.org recommends it and therefore people think it's safe. I think gnupg.org should do the contrary instead and strongly discourage using it.
It is true that there's a pretty big security hole there with "git clone
git://github.com...", since any malicious attacker can intercept that
communication. There's no checksuming or anything to make this difficult *at
What *does* suprise me is that there's a commit to specifically remove git+ssh
in favour of insecure ssh. There's no comment on why that was done either:
However, I'd recomend that you go over the proper support channels first
(rather than merely twitter) before asking that references to the proyect are
As stated on https://gpgtools.org/:
Please report any issues you find on our support platform.
Which points to http://support.gpgtools.org/.
