A bad thumbnail doesn't mean bad content. If I rejected them upfront I'm sure I could find something to replace those channels that meets the bar of "interesting", but I'd rather judge videos on the actual video and focus on how much I enjoy watching.
It is my own opinion that a creator who deliberately creates a bad thumbnail and a baited title is a bad creator, and that (by extension) I do not wish to consume their content.
There's plenty of other fish in the sea that aren't introducing themselves to me with one or more damned lies. I'm pleased to go watch what they're doing, instead.
In my world, I define myself what I consider to be a sin.
My Youtube feed has an amazing abundance of great content. I'm learning stuff with it all the time from creators that aren't prima facie lying scumbags.
Others are free to keep the likes of Scotty Killmer and Linus employed. That's fine.
They're dead to me, and I do not miss them in my life.
You can decide what's a sin, I'm just saying that fast exclusions really do eat into the watch options.
Though when I go look at the last big bunch of LTT videos I don't see any lies? Scotty Killmer I can find some lies pretty fast. "New Law Will Put You in Jail for Driving Your Car" for example.
