Basic Ethics common sense in media, before you publish something (video, article, blog), you reach out to that person/company/actor to tell them about it, and give them a heads up.
Publishing a video highlighting every error and mistake from LTT without calling Linus first was a jerk move by GN, and it means they wanted to create this crappy situation.
Intentions do matter... accidentally screwing up some graphs or failing to return a GPU because of a miscommunication is one thing, but intentionally publishing a hate piece is wrong, in my opinion
