At least in the US, most universities are also not for profit. I'd argue that Wikipedia and universities have more in common than either do with for profit companies, so I'm not convinced your examples clarify why it makes more sense to lump all of them together.
It was badly worded. I don't even know how to express this properly. It has been many years since I edited on Wikipedia, and it was on both english and portuguese. But the point that I was trying to make is that they are institutions with ideological norms and if you start deviating from them and start hammering on controversial and dangerous ideas and topics, or even just discovering and mentioning them, you can be silenced very easily.
And I don't agree with you that US universities are not for profit entities, might be on paper, I don't know. Some of them can bind the students to a long life of debt no?
