The Billet Labs prototype water block being so poorly handled was a consequence of them growing too big for Linus to manage; he hadn't internalized that they weren't six guys working out of a house anymore, but a proper medium sized business that didn't need to strain for every bit of content to keep from going under, and could afford to slow down a little to get things right. They ended up taking a break from the constant grind to reorganize after GamersNexus put out a big piece on all the things LTT was doing wrong, all the sacrifices they were making to quality and accuracy for the sake of pushing out more and more content to stay relevant, and how badly they mishandled the prototype.

Not sure Linus has forgiven GN for the "hit piece" but I think they really needed the shock of it in order to get them to actually course correct immediately rather than keep putting it off.
