Unrelated, but the last time I criticized FB on HN there was a rabid backlash along the lines of &quot;you can&#x27;t just criticize the biggest name in the valley and expect to get away with it&quot;.<p>I suspect Facebook censors things for various despotic governments in the fashion that Google does (in order to comply with local guidelines would be the excuse used here). It&#x27;s also possible that Facebook has deals with advertisers and blocks some content that may reflect poorly on them as well, but it&#x27;s nebulous.
