Nothing is being censored here; it's a simple recommendation. If they start censoring personal correspondence, they open up a huge opportunity for another option to disrupt them. It's not an impossible scenario, but it's an unlikely (and more importantly: self-correcting) scenario.
Self-correcting because frustrated users will simply start their own Google? Even if that happens, their second generation of employees will start a revolt if their company doesn't follow the latest DIE best practices.
I honestly think that only the Russian/Chinese model of a nationalized IT ecosystem has a chance to resist these trends.
Self-correcting because Google already has competition in the cloud editor space. Office suites are valuable software with an obvious business model for monetization.

That wouldn't solve the underlying problem if the nation decides some words are inappropriate (in fact, if we're thinking anti-censorship you may have chosen two particularly bad examples ;) ). It's power structures all the way down.
