@verius That was the official reason anyways. The unofficial reason is the people running the project in question was influential in socjus circles at the time and made a big stink about opinions I expressed on Twitter (that weren't related at all to the project). I'd contributed to the project before then, but went to fork it when I had that falling out.
I don't want to go into too many details because I contributed using an alias I don't really need to link back to my actual identity and end up dealing with all the baggage all over again.
