Why is there no Patreon for SimHub?

Simple question > Why no Patreon?

I have been an avid (old fart) gamer who loved making my own levels in Lode Runner on the amber monitor of my Apple 2+. I now enjoy modifying the many gadgets I built with own hands using this magical software that's been developed and maintained by one guy (my understanding, if I am wrong, please correct me).

Look, my point is that I paid him my donation X years ago for this great software and I don't mind subscribing as there's no words or review that can do it justice until you dig in and really see how multifaceted it is and worthy of a subscription.

Why no Patreon to allow a monthly subscription?

I am not suggesting Patreon only, rather just an added option?
