The focus is wavering and it is hard to make sense of much that is being said beyond: Soyuz kept bringing cosmonauts into space for 9 years - true - and SpaceX / the US would do well not to bury them just yet or disparage the accomplishments of the Soyuz program.
Fair points and all that, but the tone in this is strangely personal and even a bit whiny somehow. Just not what one would expect from an official communication at that level of responsibility. Then again, if you look at Musk's tweets some days, it can be quite a strange experience. Fun times in the space industry.
