Points 2 and 3 make no reference to previous years' data, so aren't really talking about trends. Point 1 ignores the (trend that they state) that there are more post-doc positions.
Post-docs are safer jobs, because you know what will happen at the end of them (you get kicked out and find another job). Fewer people going straight into tenure-track means fewer people spending years at an institution, not getting a job (because they lost the race) and starting elsewhere. Sounds very healthy to me!
