How many other aircraft types, lomapaseo, have repeated problems with pitot probes icing up (or indeed, any other indicated airspeed difficulties) at altitude that you have heard about recently?

there's this:

Aviation Week & Space Technology, 3/5/2007, Vol. 166 Issue 10, p62-62, 1p; Abstract The article reports on the adoption of an airworthiness directive by the U.S. Federal Aviation Administration.

The directive requires Embraer 170 and 190 operators to inspect pitot drain holes of certain air data smart probes for blockage and remove accumulated moisture from the probes' pneumatic passages. The move is a result of reports of incorrect airspeed indications caused by frozen moisture in the passages that blocked the pitot sensors.;
