He has toned it down somewhat in recent years - still blunt but that's an admirable trait for a techie (note blunt !== rude).
Indeed, people change after so many years. It is good to see that now he is providing insightful explanations, without raging or anything. After all, he is the creator of Linux and his thoughts about its directions are always super valuable.
IMO his rage posts usually still had great insightful points (cf "we do not break userspace"). The rage part was maybe unnecessary, but it wasn't the entire content of the emails.
I like the Linus that shittalks NVIDIA, though i guess that's free NVIDIA markeing, which I really do not want them to have.
