But equally, I think dismissing their concerns as a pursuit of ideological purity undermines them.

Like, I work for a FAANG, I have for a long time. But I also do good within and outside that FAANG. I do habitat restoration, I get involved with political organizations that align with my views (mutual aid, socialism, etc.)
