tson is fine even though my experience with him hasn't been entirely pleasant (there are times he REALLY needs to stfu), as are the majority of the SSF2 devs i've interacted with.
even in a post-dettadeus & APEX world where project relations aren't as ridiculous as they were in mid-2011, you can't expect them to be 100% mutually supportive of crusade after several infamous cases of our community members stealing assets indiscriminately from SSF2. simply exiling them as we did back then doesn't magically absolve all of the SSF2 team's suspicion.
anyway there's a difference between adapting a character neither party owns the rights to, and straight up copying aspects of that adaptation and as long as you don't rip them off pixel by pixel no one save for a few random brazilian children on facebook will give a hoot
integrity is a good key word here, i think.
