Like almost all situations: Demonstrate growth. No, not "subscribers go up" but actually show that you are better.

• I'll skip the anti-consumer stuff regarding merch because that has always been the brand and they at least learned to not tell people to argue against their own rights.
• Antagonistic behavior toward competitors: They are still doing the "we are the best because we are the best" bullshit in their marketing. They've at least started collaborating with Wendell from Level1Techs again which is nice. But just reaching out to the other channels would go a long way. Gamers Nexus and Hardware Unboxed are basically the kings of technical reviewing and would actually benefit Lab for a collab. And GN and HUB are very open about having group discords where all the tech youtubers talk to corroborate strange behavior or let people know that AMD fucked everyone over and they need to re-do all their work for the past week.
• Gross incompetence in their own tech reviews: They apparently have made it a subscriber benefit for Floatplane that people can pay to error check videos which... okay. And they've taken down a few videos where they REALLY cocked up basic facts and conclusions. But it is still the same mess they have always been.
• Fucking over small businesses: They eventually gave the cooler company money which I guess was nice? But it looks like they still do a "Linus is made and hates this horrible product" every few months when they want a viewership bonus and it isn't like they are going to do that to the companies that sponsor the LMG convention...

As for the really big ones? Sexual harassment and assault allegations?

A BIG first step would have been to get rid of james streib. Fucknuts was caught, on (audio part of a ) camera engaging in sexual harassment to the entire company during the fucking sexual harassment seminar the day after his report left the company because of sexual harassment from him and others. Whine about "people out for blood" all you want but that is the kind of cock up where you lose your job. Period. And the fact that people thought to record that meeting AND that linus and yvonne didn't do a "What the fuck is wrong with you?" to him for that says a lot about what kind of a culture the company has. And putting him front and ecenter on thumbnails shows how little LMG cares.

But also? Their response to multiple allegations of harassment and assault has been to attack and discredit the victim, sometimes through blatant threats toward other employees? Fuck 'em. The brand is tainted and this is the point where you pivot to right wing grifting.

Speaking of which. I forgot to mention the time D-Brand made really racist jokes about a customer's name and Linus Sebastient went to bat REAL hard with lots of "this wouldn't be a problem if he were a white man" level responses. So... I guess they already got the memo.
