I'm not trying to
dismiss her opinion. I'm surprised to one day read her essays and watch some talks, and now suddenly discover she's became another YouTube influencer.
It would be merely off-putting if it was tacked onto a video about hard, verifiable facts - but to make a video that explicitly asks the audience to trust her on her world, and then end it by saying the video itself was sponsored by a company? Surely she's aware of the optics? Even the regular YouTube influencers usually know better and skip the sponsorship section when making a complaint video.
I'm also not committing an ad hominem here (if anything, maybe some adjacent fallacy). This is the lens through which I view all YouTube channels, and it applies here, and doubly so given that this is not a video about independently verifiable facts - it's all based about an e-mail she claims she received, and she acknowledges that directly. We have to trust her at her word.
Now, I don't know about you, but if someone in one moment tells me some information, and then in the next moment starts giving me "capitalist brand advertisement speak" about some dubious product, I'm going to take it as a sign that someone doesn't actually care about my well-being, as manipulating someone into a bad deal for profit is plain malice[0]. Additionally, I might question that person's integrity - depending on obviously they're knowingly pushing a bad product, or how indifferent they are to what they're promoting. Which, in turn, will make me question everything they just told me before - after all, if they just demonstrated they're fine with lies or bullshit now, why should I assume they held themselves to the highest standards of scientific and personal truth moments before?
I'm honestly done complaining over YouTube creators; I just accepted that many of the well-known pop-sci channels turned into content marketing schemes. At least I stopped being surprised by exaggerations and inaccuracies in the main parts. I commented this time only because I totally didn't expect to see a reputable scientist doing this kind of stuff.

[0] - Yes, I stand firm on this, and yes, if you scale this view up, you end up considering the entire field of "marketing communication" (covering a subset of intersection of sales, marketing and advertising) as a cancer on modern society. I wrote an article about this some time ago, which I've been told has apparently popped up on HN last week.
