I don't have much insight into European companies and how strongly they protect speech as a matter of policy, but rulings by the EU have been extremely discouraging. Here are some examples:
1. The EU's "right to be forgotten" can compel the removal of content that is both true and relevant. [1] In the US, my right to publish true facts about you trumps your right to have them swept under the rug.
2. The EU can compel publishers to remove content they deem "hate speech." [2] If you look up the EU's definition of hate speech, it actually sweeps broadly into what the US would call protected speech. For example, Germany's "incitement of popular hatred" [3] can be used to prevent newspapers from advancing the argument that migrants are disproportionately likely to commit crimes. Since there is no truth defense against hate speech accusations (unlike libel in the US), a newspaper that is dragged into court on hate speech charges couldn't defend itself by proving that what it wrote was true.
