If you were a bank or a energy company would you want your advert on potentially sexual content, and I use that in looses possible sense.
It stems for an incident years ago where a "journalist" spam refreshed a ISIS video on YouTube until they saw a VW advert and they ran a massive story about VW financing ISIS via YouTube. I may get getting some details wrong about the story.
That hasn't been my experience at all. I feel like you don't actually use Twitch, but even if you're right it's "tu quoque". Neither party should be showing sexualized content in a space largely occupied by children.
