Mate, the video is packed full with content and tons of issues regarding LTT. Just take the time and watch it, there is barely any fluff in there.

Quick summary of issues:

• Tons of data mistakes that are either unaddressed, only brought up in a footnote or in a tiny text popup. Often on videos with a million views already, so hardware buyers make the wrong decisions. Not even small mistakes, like one slide showed a 4090 to be 300% faster than a 3090 Ti, which is simply untrue. Even their own internal numbers are inconsistent between benchmarks
• Rush of getting videos out, employees of LMG say they don't have time to do quality control, it's too much. Like 25 videos per week or something over all channels combined
• LTT received a custom waterblock prototype to test on a 3090 Ti (they received the GPU too), they tried to test it on a 4090, turns out that didn't work well (while also ignoring all instructions), then said the product is shit and nobody should buy it. Instead of sending the prototype back like agreed upon they auctioned it off and gave the money to charity (allegedly). If really unlucky a competitor might have bought it on that auction to duplicate the design. After the GN video Linus said they already agreed to pay the prototype company.. while the prototype company said they just got the email from Linus and haven't even replied to it. So straight up thieving and lying and destroying the reputation of a small indie company
• Problems with conflict of interest. LTT has Noctua branded tools on sale in their shop, but also reviews their fans. Or have a big investment in Framework laptops, while also reviewing laptops of other brands. It's a dangerous line

I probably forgot several points here, the video really is full to the brim with objective issues. I unsubbed from LTT and I'll never watch any of their videos again at this point.
