Clickbait remover is a great extension that was made before dearrow. If you prefer that simple approach, it's made for you

The crowdsourcing in dearrow is more about titles than thumbnails, which is something clickbait remover is not able to deal with.

Response to edit: I'm not sure I understand your point. If you don't think crowdsourcing is beneficial to you, you should use the other extension. The whole point of this extension is for the crowdsourcing, so most people using this extension are do have those enabled.
