Use DeArrow if you're so sensitive to it. And like I said, it is necessary if YouTube is also a money making endeavor. Casey likely makes little from his videos so he doesn't need to have clickbait thumbnails.
DeArrow gives a YouTube page with rageslop that has been marked as rageslop. I do not need an addon to determine that, I need a feed that does not serve it to me in the first place, and that means curating my feed by rejecting certain videos and channels.
And this goes back to my point, if you are a competent engineer, why are you spending time producing rageslop for money, rather than, you know, doing the engineering.
There's also money in being an engineer. If he makes so much more money as YouTube rage farmer, then I'd be surprised, but it still wouldn't change my perception of it being degrading work, harmful to his credibility and probably harmful to his mental health too.
