The problem is that, as Hardware Unboxed and others have demonstrated in their disputes with nVidia, if you're not releasing reviews on the manufacturer's schedule (e.g. samples available early and then following embargos for releases) then there's no viewership for your videos.
Literally if you haven't made and released a video in the two days after the embargo drops, you're not going to get substantial views, at least not enough to be a household name.
So, even if you are independent, you play the game and you try not to p*ss the vendor off while also maintaining independence.
Ultimately, the Intel videos by LTT and GN weren't a full review, and both were previews. But importantly, they were previews in a way that we really aren't used to big corporates allowing, and that's a positive change. While both channels were clearly being friendly, I don't think there was anything shill about it. The vendor set the bounds of what they could show in exchange for the right to share what was allowed, but I didn't see them reading from the hymn sheet. Heck, Intel spoke openly things that previously nVidia and AMD would have been trying to hide or avoid, it's refreshing.
You take the videos for what they were, a preview under specific conditions. Later on there will be full reviews, unconstrained benchmarks and time for a full critique. But I bet with great certainty, most people won't ignore these preview videos, or any "day zero" reviews, in favour of channels that don't work with Intel PR.
