There are definitely ridiculous people all throughout the world, the US doesn’t have a monopoly on them. We just have more people than like 95% of other countries (IIRC only China and India have more people) and those people happen to have wide access to tech, and money to do dumb shit like this.
A lot of creators have just turned into corporate shills. I stopped watching ETA Prime’s channel about tech reviews because it was becoming pretty clear that mostly everything he got was paid for by the company. Also, most creators are putting their own ads into their content.
