GN wasn't the first to break the story the 13/14th gen was defective. The thousands and thousands of users experiencing the issues collectively noticed pretty quick. If anything, there was a period where he was saying "We've talked to Intel but we won't say anything yet until they do."
The only real problem with GN is Steve is a bit of an egotist when it comes to content creators who do less technical analysis, like LTT or Jayz.
He never really got over the stuff with Linus and doubled down on stupid things.
I think they both have a great place in the tech scene and LTT's videos of recent have been a lot better quality and researched then yesteryear.
