Low EQ Silicon Valley refuses to use its influence to affect political change in any meaningful way. Or even just political awareness. Ironic when you consider this political/social passiveness enables the same surveillance capitalism that this community is constantly complaining about.

The experiment was effectively a ban on that small subset of political content that would otherwise be generally within the guidelines.
