This isn’t true for all streamers, just those with partner contracts from Twitch. They are the ones that are required to run ads a certain amount, I think below that they have the option to run ads but aren’t required to but also if you don’t run any ads Twitch will just start putting in ads on its own. And theres no control from the streamers over ads that show when joining a stream, those are always there and in my opinion are more annoying cause it makes it more annoying to switch between streams.
My problem with it is the whole purpose of what the device does based on the post is stupid. It just puts a notification on the screen as a way to try and use social pressure to get people to stop vaping. But that doesn’t work cause no one really cares if you vape or not. Some people might even think it’s cool or might turn it into a game of trying to vape without setting it off to impress their other friends who vape. I graduated highschool in 2019 and people definitely vaped and the only people they really cared about hiding it from were the teachers, no other students cared at all. So because of all of that this kind of device is just a waste of money that could be better spent on educating kids on how vaping is bad, just like what we did for cigarettes that worked so well.
