I read all of your points as criticisms of Linux. That is disappointing.
I read most of his points as being factual, some of which might be comparisons to and constructive criticisms of Linux. Not disappointing at all.
I don't think anyone could argue that Linux's interfaces are stable. What, with the lead promoter and configuration manager on record as saying stability is not an objective.
[And as someone who maintains kernels for a living, I can tell you with no uncertainty that he's meeting that non-objective really, really well.]
