"We also as individuals [without billions] have fairly limited capacity to directly act against these things. I donate a fair bit to the EFF for instance and I've sent outreach to representatives multiple times over the years for specific bills and when its possible I vote against surveillance." - from a parallel thread I was commenting in.
I'm totally fine stopping at minimizing my culpability. I sleep just fine at night and don't really jump at purity tests like you seem to want. I'm not other people's savior and I don't want to be. If you want to put your energy into that, I support you.
