Reaction videos are the lowest form of content imo. Far lazier and far less interesting than speedrunning, coding streams, reading/discussion streams, etc. (Not that I find Twitch streams generally compelling, either.)

And payments to streamers aren’t donations in the sense of charity and don’t claim to be. They’re tips paid to entertainers, like money tossed into the hat of a street musician. It’s a different model than wage work but it’s not like a scam or a trick or something.

Using those tips to employ the wage labor of others (e.g., video editors) is exploitation, though.
