Sales and politics are not avoidable, I agree with that. While a scientist might have to dreadfully deal with salesmanship now and then, it shouldn't be affecting the day to day. We have procedures to isolate these things from core business, so we can focus without the hyper-selfawareness of salesmen. If you have to be constantly getting the most eyeballs, attention, upvotes, in everything you're doing, it will change you and your work. Look at the conversational tricks that people use to get ahead at your (least) favorite social media, and see which type of personality is promoted there.
What I'm trying to say is, while the medium doesn't change core mechanics of human behavior, it distorts and accentuates – there is, for instance, a difference between tiktok and a novel. And we do have power of mediums, we can choose to engage in different types, and we can lobby for digital mediums to change. So pitting youtubers against the algorithm (just pimp your quantum physics lecture with an O-face thumbnail) isn't the only way forward. There's also "here's how YouTube could be better" or "we need a better alternative for this type of content". Unfortunately, we have almost 0 visibility and control over the algorithm so there's very little behavioral analysis that can be done.
