I don't think its inherently because of corporate censorship. I think it is because other people are flagging and complaining about your posts. After too many they technically have to respond.
It's the environment of FB in general. It's a lot easier to trying and anonymously censor the opposition.
I told the new me,
"Meet me at the bus station and hold a sign that reads: 'Today is the first day of the rest of your life.'"
But the old me met me with a sign that read: "Welcome back."
