Pardon the off-topic post, but what did nv do to him?
NV's PR can be very difficult to work with by all accounts (opinions of others, not myself). They demand to control their messaging and have very little tolerance for folks who don't toe the line.
The only real power that PR folks have is access to HW and people and the occasional junket.
Charlie calls things as he sees/perceives them and doesn't care about toeing the line to make a company look good. He's also not what I'd call your average reporter (not bad or good, but very different).
You can see how that might cause a collision course.
My understanding is that NV's PR made a decision to freeze charlie out and try to prevent him from effectively writing about NV (unless he started to behave 'better' from their perspective). You can see that in a lot of what he's written - he never gets info from NV PR directly and he's almost throwing it in their face that he's still able to talk about their GPUs without them. It's hardly a secret.
Anyway, I'm sure Charlie has quite a bit of respect for some of the folks at NV, but he sure as hell doesn't like some of their PR folks.
With the stuff about bumps, I think Charlie just got curious and wanted to dig and find out what was going on. When NV started obfuscating, that just encouraged him to dig further and find out the truth.
