Look how Silicon Valley folks treated Brandon Eich when he made a donation to the majority side in a California proposition. It's not just academia where you can't speak freely.
Ugh. The Brendan Eich issue was about freedom of association -- in particular, the right of Mozilla employees and stakeholders not to be associated with the bigoted groups (and their hateful TV ads) Eich was supporting -- rather than freedom of speech. If you're still not clear as to the distinction, please see: https://xkcd.com/1357/
Freedom of Association is the right to join or remove yourself from a group for the sake of collective right.
