Corporations aren't people, but in the end it's still people that are responsible for this crackdown on liberal content. It's someone at Facebook making these decisions, someone who is a person, we just don't know who the responsible person is.
Zuck has shown he's more interested in money/power than the well-being of other humans (the "dumb fucks"), he's cozied up to Xi Jinping and Donald Trump.
Donald Trump's co-opted the religious nuts that are anti-abortion and anti-LGBT, and Zuck is more than happy to please him rather than risk prosecution and losing his money or freedom. What a model of cowardice.
And Meta in particular - just look at the founder/leader. The “CEOs are all sociopaths” trope exists because of people like Zuck.
