I think we'd have a big problem at the beginning, since just as when we remove the main person from the family, there is usually a period of restructuring.
After the restructuring is done, applications and users should also understand how STINC's post-exit system will work.
I believe that the actions of users and applications would change drastically, neither for positive nor for negative, but for adapting to the new reality. We would also see several people going to the forks that were created by Steem, and consequently we would have more competition.
