I am assuming the person was referring to "uBlock Origin" given that "uBlock" has already shown it can't be trusted, maybe I am wrong and he was indeed referring to "uBlock".

The repo was handed in good faith, not for the sake of financial gains. It turned out to be a mistake, from which I learned. That was now nearly seven years ago. If the take away from that event after years of never breaching user trust is that "uBlock Origin can't be trusted in the long run", that's pretty harsh.
