TL;DW: GN called out LMG for notoriously sloppy content recently, which is caused by LMG top management imposing high weekly video quotas. LMG team is also not happy with these deadlines and have said before it leads to rushed content.

Then LMG also did a big fuck up with a Billet Labs (small company) prototype water block. The company sent them a review prototype for a 3090ti monoblock, but LMG knowingly gave no fucks and tested it on a 4090. When it obviously didn't work as expected LMG just shat on the product and gave a bad review. Not only that, they ignored requests to return the prototype, and their negligence went as far as them auctioning the engineering prototype at LTX.

There's more incidents (like shitting on a mouse before properly unpacking it first, poor correction for mistakes, several inaccuracies in each video, etc) but you'll be better off watching the video, it's good.

Linus has responded, but he just dug a deeper grave after GN tore apart his shitty reply on their newest video.
