Clickbait remover uses YouTube’s auto generated ones, which while are seemingly random, are not. They use some algorithm to target faces in exaggerated expressions.

DeArrwow uses actually random ones (and then a user can submit specific timestamps if there is a better one). It’s noticeable better on many channels imo. It also let's us do things like make sure the random thumbnail is not in a sponsor using SponsorBlock data

It never asks to access to all sites, it only optionally let's you add support for additional sites such as different Invidious instances.

Support for invidious is not actually done yet, so right now, it never asks for permission for any new sites anyway
