GN has always had respect. Linus has even directed people to GN on multiple occasions. Steve from GN was invited to Linuses roast and I thought they did some stuff together (maybe one of the scrapyard wars?)

I guess my point is: there has been mutual respect from both of these guys for each other. Which makes the fact that Steve didn't give Linus a chance to comment/add some context to GN's video pretty shitty.

No he doesn't "have" to reach out, but it seems really odd that they didn't given their working relationship to date (even if it's just two business men in the same field that knows each other).

You don't do a call out video without a heads-up...unless you 1. Are trying to do a hit piece 2. You think he will provide enough context to change your mind and you'll have to scrap your video or 3. You are worried he'll scoop you or have too good of a response

Its worth noting GN probably sees LTT labs as an existential threat once they get going.

It doesn't mean their concerns are valid now, but this isn't some completely altruistic "think of the consumer" situation.
