2 further interesting points from the same article above in titania's post.
1. the conclusion of poor maintenance of the pitot tubes is based on analysis of similar pitot tubes which have been confiscated by the justice department and which seem to have been poorly maintained. Later on in the article reference is being made to the cleaning of the pitot tubes which is alleged to have been in accordance with an agreed schedule (which by deduction could therefore have been insufficient).
A further observation at the start of the article where the Secretary of State for Transport (of France) has asked for continued search for the wreckage. That sounds like good news....
