Earlier quoted context omitted.
We've all gone through it :-( Happy users of the (really good) software until our hardware gets "too old" and the inevitable rug pull.
Uncompensated volunteers dropping support for a 7 year old device that is shortly going to be unsupported by the manufacturer isn't a rug pull. Entitlement can be wild, volunteers are volunteers. Consumers of volunteer output are free to support their use cases themselves on their own time. Find an ARM Mac used (like an M1) and upgrade.
And throw away perfectly good hardware.
