to rot in jail for the rest of their existence
Because later on, if they were found to be actually innocent - the person rotting in jail can be released and compensated (to whatever extent false imprisonment can be compensated).
If they were executed, it’s over. The injustice can’t be remediated in any way.
As Linus (and other YouTubers for that matter) have said, awful thumbnails and clickbaity titles work.
And when YouTube is a side gig you can refuse to do it on principle, but when you need to pay 100 folks (in case of LMG) - I don’t think it’s much of a choice.
