So random youtuber gave you something of value - something that saved you hundreds of dollars from not having to get a professional repair - yet you have something against random YouTuber getting paid?
Watching ads simply isn't something I'm willing to consider. Like if the transaction was "have someone spit in your face and in exchange you get a how-to video and they get paid based on the amount of spit you get in your mouth", I'd feel similarly about that business model.
