This could happen and maybe have already happened with a few patrons, but to unsubscribe from something you will have to be subscribed first, and in this thread most of the critics play it for free, so...If negative reaction is not justification for removal, what is?
Dev: *Puts something out.* Enjoy!
Audience: We all like this, but hate this part.
Dev: Well too bad, I'm going to keep putting that part you hate in.
Audience: *Confused unsubscription noises*
And IIRC in their Discord (where many of their patrons participates) the conclusion was reached to keep his character despite all the controversy and criticism that he has generated. So those "*Confused unsubscription noises*" don't exist atm or at least are clearly a minority.
