They did not secretly introduce exploitable bugs:

Once any maintainer of the community responds to the email,indicating “looks good”,we immediately point out the introduced bug and request them to not go ahead to apply the patch. At the same time, we point out the correct fixing of the bug and provide our proper patch. In all the three cases, maintainers explicitly acknowledged and confirmed to not move forward with the incorrect patches. This way, we ensure that the incorrect patches will not be adopted or committed into the Git tree of Linux.

A lot of horrible things have happened on the Internet by following that philosophy. I think it's imperative to learn the rigorous facts and different interpretations of them, or we will continue to great harm and be easily manipulated.
