I get your criticism and agree with it. I've slowly watched even the most serious creators I follow on Youtube succumb to it over time, in varying degrees. Unfortunately, I think everyone caves to the algorithm eventually. When you think about it, it makes some sense, given that they often will put 100s of hours into a single video when you count research, scripting, videoing, editing, etc. And if it's their job, playing by the rules to work the algorithm is literally putting food on their table. So, I get it. They don't like it any more than we do (do you think Lake Speed or Project Farm ever envisioned themselves taking selfies making silly faces for thumbnails?). A little part of them probably died when they made their first thumbnail with a stupid face. But alas, conform, or get left behind. If you don't do it, someone else gladly will and will take your place without batting an eye.
