The platform is getting via advertisements in their apps is not a bad deal, the problem with their approach is that the ads are insufferable which means that there is no skip and every time the user leaves the app, they need to log in again. Stream sites that are accepting cryptocurrency donations are not that big because most of the time it is frowned upon their community because most sites do not get a cut from crypto donations. I have to disagree with it not being the best idea because I think incent just had a bad execution of their platform but if it was otherwise, it will be praised.
I don't mind advertisements, as long as they aren't the usual drab. A few places actually do advertisements well, but its not common practice. Its usually using the business model of lets make as much money as possible, and we don't care what we advertise, which is something that I can't agree on. Adverts should be handpicked, and relevant to a websites users. No advert that is unrelated should be displayed.
I don't think its frowned upon by the community, rather its frowned upon by those that own the streaming sites since they aren't getting a cut. Although, there's ways to incorporate Bitcoin into the streaming site, and allow a cut very much like you would with traditional currencies.
I personally don't think its a good idea right now. Not in its current climate, because I'm just trying to think of the demographic of Bitcoin. Most of its users prefer privacy, and tend to stay away from revealing their identity. I suppose streaming doesn't always have to reveal your identity though.
That's not suggesting that Bitcoin's demographic wont change down the line though.
