They were until maybe a few months ago when Linus's "Trust me bro" scandal (using that term very loosely) happened. IIRC it boiled down to questions over LTT Store not having an explicit warranty policy on certain then-hot/new items. LTT seemed to be resolving issues as they came up but people in the community were expressing concern over the lack of a concrete policy that they could point to. Linus then went on WAN Show to say basically (paraphrasing) "Regardless of if we have a written warranty, we could just break that agreement, companies do it all the time. So if you have a problem, you either trust us to make you whole or you don't." Steve came out with a response video that boiled down to (again, paraphrasing) "No you do actually need to have a written warranty, it is very important both legally and for community trust".
EDIT: Video and timestamp in question. It was with regards to the LTT backpack launch, also it was almost exactly a year ago.
That cascaded in to future responses, and the clips shown here from WAN Show show Linus implicitly (but obviously) referring to Gamers Nexus - and Steve in particular - when he talks about handling the situation unprofessionally and without journalistic integrity. I was sort of on board with Linus during the original bout, LTT Store by all accounts has been pretty solid for its customers and it's obviously a very large and successful part of the business. But the harder Linus leans in to memeing on 'Trust me bro' which was a bit of a PR shitstorm, the harder it was to sympathize. He has continued to bring it up, and now actively calling out the integrity of GN was a huge mis-step. I'm fully with GN on this one, and I didn't even know about most of the technical errors (although I was aware of some, between listening to WAN shows and seeing some on previous GN videos), which furthers Steve's point about the method of correcting these errors being severely lacking.
The story about the giant monoblock cooler being auctioned off at LTX when they literally did not have permission to do so and indeed already agreed to return it since it was the company's best working prototype... that's so fucked I can scarcely believe it's true. I hope it's not or there is some kind of misunderstanding there, because if it's true that's a colossal fuckup on LMG's part that the community really should not forgive them for, and I could see totally drying up any interest from other small companies wanting to show off their cool niche engineering projects by sending them to tech media. LMG is one of the biggest players in the space, they can't afford this "go fast, break stuff and move on" attitude.
