The left (or at least the fairly broad swath I'm acquainted with) has been mostly hostile to crypto and skeptical of "effective altruism" for years. I don't know anybody on the left who would have identified SBF as "one of the good guys" before this all came out; "yet another tech bro who thinks he knows how to save the world" is more like it.
I've only ever heard of left-leaning publications that find excuses for him. Maybe individuals you are acquainted with are as you said but that wasn't what me or parent were talking about
