'It is not me he is grifting' is a shit take, mate.
That's right it's not me so I don't care, it's not me that even after 2+ years without an update still chooses to support them, it's not me that after learning of the decision to remade a big chunk of the update still continued to support them, it's not me that even seeing every day that the progress they made looks really low and insignificant still by my own decision, supports them.
No I don't feel sorry for someone that burns their own money for a promise of getting a treasure later.
No I don't feel sorry for someone that even with so many things screaming in their ears "Man, I think this is a Scam" still decides to not hear them and support them anyway.
And even if they were that ingenious and/or innocent and never expect that such a thing could happen at least they would learn a very valuable lesson that is much more important and useful in the future than my "sorry for them".
